Incidents have occurred between the Seaworld orcas and their trainers since captivity began. The majority of incidents can be backed up if research is done correctly, many of them done from Seaworld's own animal profiles.
Although some of the incidents say bumped, fluked etc and it may seem like nothing, remember these are huge animals and these actions were directed at trainers, the majority of those types of incidents have also been taken from the Seaworld Animal Profiles who deemed them warranted to be permanently mentioned.
Those animal profiles are linked to each incident where available so you can check out what Seaworld themselves too.

16/11/1986 Kandu V SD 9-year-old female Kandu 5 pressed her snout against trainer Mark Beeler and held him against a wall for a few seconds during a performance before several hundred spectators.
In November 1987 SD things opened up at Seaworld San Diego, newspapers reported on at least 14 incidents that hadn't been documented. On November 21, 1987, Orky the mature five-ton male came crashing down on 26-year old John Sillick during a show in San Diego. At the time Sillick was riding on the back of a female orca. It was a crushing blow. Sillick almost died. He had severe fractures to both his hips, his pelvis, ribs and legs. After six operations in fourteen months, according to Sillick's lawyer, he was "reconstructed" with some three pounds (1.4 kg) of pins, plates and screws, including a permanent plate inserted in his pelvis and all his thoracic vertebrae permanently fused. He can walk today but his activity is limited.
After Sillick's injury, changes were finally made at Sea World. Sea World's owner, Harcourt Brace jovanovich (HBJ), the book publisher, stepped in with chairman William jovanovich calling the shots. The trainers were told to stop riding the whales, to stay out of the water with them, and to go back to the old training methods. Chief trainer Butcher was dismissed along with long-time zoological director and veterinarian Lanny H. Cornell and Sea World San Diego president Jan Schultz.
Various reasons are given for the accidents, but none can be fully explained. Some could have been simple miscalculations on the part of the whales, or missed signs. There might also have been poor signals from inexperienced trainers. The Orky incident with John Sillick did not surprise trainers who knew Orky, his history and his recent circumstances. Captured in April 1968, Orky had grown up with Corky at Marineland of the Pacific near Los Angeles, California. Soon after becoming mature, in 1978, he pinned trainer Jill Stratton on the bottom of the pool, nearly drowning her. "After that," said long-time Marineland head-trainer Tim Desmond, "we didn't regularly do water work with him because we didn't feel it was safe." On January 20-21, 1987, three weeks after Sea World owner HBJ bought Marineland, and promised not to move the orcas, Orky and Corky were trucked to San Diego, to join several other orcas. The new situation new breeding age females and much breeding activity - altered the social interactions of all the whales. But probably more important, Orky was being asked to perform according to the Sea World method with several trainers in the water. For Orky it had all happened almost overnight. Some Sea World trainers contend management was in too big a hurry to break in Orky. Did Orky have trouble making the transition? It is difficult to determine, but Robert K. Gault, Jr., then Sea World's president, admitted to the New York Times that they may have over-emphasized the importance of the entertainment, adding: "We did not have enough experienced trainers."
When Butcher had brought in his new methods and tried to standardize training in all four parks, he alienated several veteran trainers. In one year, about 35 trainers departed, according to Bud Krames, a senior trainer who left because he didn't agree with the system. New trainers had to be hired. Three of the five trainers in San Diego had three months or less experience working with orcas. Sillick, a veteran by comparison, had less than two years. In the year following the accidents, some of the injured trainers began to blame Sea World for not warning them about the "dangerous propensities of killer whales" as one lawsuit put it. Jonathan Smith's lawyer charged that Sea World and HBJ "negligently and carelessly owned, maintained, trained, inspected, controlled, supervised, located, transported and placed" the orcas, thereby exposing Smith to serious injury. Sillick and Weber also filed lawsuits. All three were later settled out of court with gag orders imposed. Following the terms of their deals with Sea World, the lawyers have refused to reveal any more than the basic details of their clients' cases. This means that no one can know any findings behind these cases; no one can learn or benefit from the thousands of pages of prepared evidence.
Way back then there were incidents causing the same concerns as today.
After Butcher left, Sea World revamped the training programme. Under new chief trainer Michael Scarpuzzi, they returned to a simple, consistent approach of rewarding each behaviour. Instead of going into the water, trainers began directing the whales from the deck with hand or underwater acoustic signals. But less than half a year later, they were back in the water. This time the animals were being taught to focus their attention on the main trainer on stage, ignoring trainers in the water. All of it was conveniently just in time to celebrate Sea World's 25th anniversary with a new orca show. The show must go on! Only time will tell if the current training programme proves safer than those of the past.
Only time will tell if the training programmes prove safer was said back in 1987. Well we know the answer to that question. NO IT HASNT as we shall see
03/04/1987 Kandu V /Keanu SD
A six-ton orca suddenly grabbed trainer Jonathan Smith, 21, in its teeth, dove to the bottom of the tank, then carried him bleeding to the surface and spat him out. Smith gallantly waved to the crowd - which he attributed to his training as a Sea World performer - when a second orca slammed into him. He continued to pretend he was unhurt as the whales repeatedly dragged him 32 ft to the bottom of the pool. Smith was cut all around his torso, had a ruptured kidney and a six-inch laceration of his liver, yet he managed to escape and get out of the pool. Later reports indicate that the whales involved had been 10-year-old female Kenau and 9-year-old female Kandu 5.
A suit filed in March by ex-trainer Jonathan Smith is pending in Superior Court. Smith alleged that injuries inflicted by two of the whales during a show last year were caused by the negligence of the company.He sued Seaworld. His suit says officials concealed the "dangerous propensities of killer whales" from him and assured him that it was safe for him to participate in the shows, even though he had no formal training.
15/06/1987 Kandu V SD Trainer Joanne Webber, 29, suffered a fractured neck when 9-year-old female Kandu 5 landed on top of her and pushed her to the bottom of the pool during a practice session. Webber had five years experience working with orcas.She sued Seaworld in a lawsuit filed Tuesday in San Diego Superior Court that Sea World and its parent company, Harcourt Brace Jovanovich, knew that the whales were "ferocious and dangerous" and were "likely to attack and injure human beings," but induced her to enter the pool by telling her the whales were "safe" and "gentle."
Webber's injuries were aggravated by Sea World personnel who delayed treatment, insisting that her wetsuit be removed at the park so that it would not be damaged by medical personnel who would try to remove it at the hospital, the lawsuit says.
Webber, who returned to a job at Sea World after her health improved, went back on medical leave last week after Sea World officials requested that she either take an office job at the park or go back in the water with the whales, according to Paula Tupper, an associate in the law firm of Patrick R. Frega.
Her injuries included fractures of the first cervical vertebra, contusions of the skull and scalp, and bruises to the left arm and shoulder. After a year, two cracks in a vertebra in Webber's neck still have not healed completely, and she has lost 50% of the side-to-side motion in her neck, Tupper said.
'In Great Pain'
Webber was able to free herself and get out of the pool after the whale attack, Tupper said. Park personnel then allowed her to walk about 50 feet from the pool to an enclosure, where she was told to remove her wetsuit, Tupper said.
"In great pain" and unable to comply, the lawsuit says, she was "stripped of (the) wetsuit by Sea World personnel." Tupper added that Webber was told to dress and walk about 200 yards to a waiting ambulance.
The lawsuit also names 35 unidentified defendants and asks for unspecified damages.
They also knew that the whales were "capable of uncontrollable erratic behavior, aggression, and attack," but nevertheless placed a newly acquired and "known dangerous" male whale in proximity to female killer whales, thus increasing "the likelihood of erratic behavior and attack," the suit alleges.
Webber never would have gotten into the tanks if she had known the facts, the suit contends.
28/09/1987 SD Trainer Mark McHugh was bitten on the hand while feeding an orca between shows.
As you see above all 3 cases were settled out of court with gagging orders incorporated Following the terms of their deals with Sea World, the lawyers have refused to reveal any more than the basic details of their clients' cases. This means that no one can know any findings behind these cases; no one can learn or benefit from the thousands of pages of prepared evidence.

2000 Ikiaka SO Young male Ikaika has a history of aggression, often of a sexual nature, which began with an attempt to breed a young calf at SeaWorld shortly before his transfer to Canada. SeaWorld's veterinarians then sedated Ikaika twice daily with Valium to "try to mellow him out." "We've already seen some of the precursors (of a human attack) up there, meaning he's grabbed boots, he's grabbed targets, he's grabbed an arm before," Chuck Tompkins, a senior executive at SeaWorld and head animal trainer, said in an affidavit. Those are signs Ikaika is testing his environment and seeing what he can do, Tompkins told the court. "And if you're not aware of all the little things that killer whales do, you can get somebody really, really hurt," Tompkins said in his affidavit. "I've got grave concerns on the safety of the staff and inevitably the safety of the animal because of the lack of change. News report on the court case with Marineland

2002 Ulises SD 25-year-old male Ulises was doing a waterwork session in "A" pool. His trainer was on his back and wanted him to move closer to the acrylic by giving him the cue to "steer" him in a directional way. Ulises did not know this behaviour. Instead, he took this as a finger roll, the trainer fell off and Ulises began to go on a descent. He ignored the trainer on the porch trying to receive him and turned around to go back towards his trainer in the water. He turned ventral and scooped her up, and then started to become erect. She was able to get off at the porch and reinforce him. He was calm. SW Animal Profile
31/07/2002 Orkid SD 13-year-old female Orkid was given the opportunity to rehearse pulling a trainer into the water by her bootie (sic!). After placing a foot in Orkid's mouth several times Orkid pulled the trainer in the water and pulled the bootie off. SW Animal Profile
2003 Kayla SA 14-year-old female Kayla had refused multiple separations prior to the show opening. She proceeded to perform abnormally high bows on a fast swim cue, came back and received an LRS(* see below), performed another set of bows on the fast swim. She was then asked for a line up, tactile was applied and she lined up with a slight lean. As the trainer backed over the wall, she then came out of the line up towards him with her mouth open. No contact was made. She then performed a head bobbing behaviour and split to the front pool. After several minutes staff attempted control and they were able to separate her to the back pool to continue the show. SW Animal Profile
01/08/2003 Kyuquot SA During a portion of the show, 16-year-old male Kyuquot refused to let a trainer exit the pool. He did not become aggressive, but refused callback tones and slaps, and would not allow the trainer to leave the pool. The trainer was able to get close enough to the glass to pull himself out very quickly, and Kyuquot then proceeded to fast swim around the pool, followed by sliding out at stage. SW Animal Profile

He ignored a hand slap and tone before responding to a second tone. SW Animal Profile
Summer 2004 Kayla SA During a night show, 15-year-old female Kayla had performed the first two songs of the show acceptably, and then did two ventral squirt bow cues. She responded well to both LRS that occurred, and then received a primary reinforcement for the second LRS. She was then asked for a fluke splash to the back, and then asked to separate to the back pool. During the separation attempt, she lunged at her trainer, although no contact occurred. After several minutes, she separated into the back pool, allowing the show to continue. SW Animal Profile
18/10/2004 Kasatka SD A trainer was attempting to Scuba dive in "E" pool with 28-year-old female Kasatka and her 3-year-old male calf Nakai. The trainer did not have approval to swim with fins. He may have brushed her with his fins and she became aggressive, mouthing fins and Scuba gear. She eventually responded to a hand slap stage call. SW Animal Profile
01/04/2005 Taku SO A SeaWorld Orlando trainer is expected to return to work soon after being injured by an "overly excited" killer whale, a theme-park spokeswoman said Sunday. 11-year-old male Taku, one of nine at the park that go by the stage name Shamu, swam rapidly past the trainer and circled back, bumping him repeatedly during the Shamu Adventure show at 12:30 p.m. Friday, spokeswoman Becca Bides said. "The trainer maintained control of the animal," Bides said, and the show continued uninterrupted. The trainer, supervisor Sam Davis, was taken to Sand Lake Hospital for unspecified minor injuries and released the same day, she said.
Additional eyewitness account: "The trainer and Taku were about to slide on the slide out at the end of the show when Taku completely stopped and started "bumping" the trainer. The trainer was male and he finally swam out of the tank. I knew something was wrong because non of the whale except Kalina wanted to perform. Then they finally got Taku out to splash people at the end of the show, when this incident took place

06/10/2007 Tekoa LP A trainer at the Loro Parque theme park on Tenerife is in hospital after she was injured this weekend during a training session with 6-year-old male Tekoa at the centre in Puerto de la Cruz. The Canarias 7 newspaper says the incident happened at the pre-show warm up on Saturday, when the orca crashed into the trainer, injuring her right lung and breaking her forearm in two places. She was rescued by two colleagues after the marine mammal dragged her down to the bottom of the pool. The trainer is now said to be stable after surgery on Saturday. Later it becomes know that the injured trainer is 29-year-old biologist Claudia Vollhardt from Germany, who has worked at the park since 2003. OME News write that it was a male orca that hit the trainer and dragged her down after the impact. Then that same animal grabbed the trainer by the arm and brought her back up to the surface.

24/12/2009 Keto LP KETO KILLS ALEX MARTINEZ A Loro Parque trainer has been killed by one of the whales during a training session. The trainer was 29-year-old Alexis Martínez, and the accident occurred at 10.30 am this morning during the first training session for the Christmas Special planned for the New Year. The other 7 trainers were also present in the training session. As far as can be determined right now, Alexis was hit by 14-year-old male killer whale Keto, and his death was caused by drowning because he was under the water unconscious for several minutes before he could be rescued. The autopsy report on Martínez was telling and states bluntly that his was a "violent death." It describes multiple cuts and bruises, the collapse of both lungs, fractures of the ribs and sternum, a lacerated liver, severely damaged vital organs, and puncture marks "consistent with the teeth of an orca." It concludes that the immediate cause of death was fluid in the lungs (i.e., drowning) but that the fundamental cause was "mechanical asphyxiation due to compression and crushing of the thoracic abdomen with injuries to the vital organs." In other words, at some point Keto probably slammed into Martínez with such force that he caved in his chest. Outside Magazine
2010 Orkid SD 21-year-old female Orkid has been sliding out in various slide-out areas on her free time which has resulted in possibly dangerous scenarios for guests at the Dine with Shamu area.

Just to establish fact as I know Seaworld has stated it is a lie - the autopsy report does indeed state Dawn Brancheau's left arm was separated from her body as in the picture above. . You can see from Tilikums Animal Profile it just states, grabbed pony tail, pulled in water, held trainer underwater, carry tow trainer. For Keltie Byrne it says be advised Tilikum was involved in an accidental drowning and for Daniel Dukes it says drowning no specific behaviour noted. As you can see from the records, autopsy reports etc, above this is hardly giving the trainers a full view of what happened and what danger they could be in, other than telling them Tilikum had his own protocol, it doesn't tell them why.
It also states during times of frustration due to social stress in the environment, Tilikum has demonstrated aggressive behaviour by mouthing the stage, vocalisations, deep fast swimming, tightening body posture, banging gates, and sometimes lunging towards control trainers. It also says occasionally he has displayed possessive behaviour of objects and whales in his environment.
This is the show prior to Ms Brancheau's death which shows social stress in the environment. One orca rammed up out of the water and control lost so much the trainers left the stage
The report on the incident states
Finally—now holding Brancheau by her arm—he was guided onto the medical lift. The floor was quickly raised. Even now, Tilikum refused to give her up. Trainers were forced to pry his jaws open. When they pulled Brancheau free, part of her arm came off in his mouth. ( I suspect this is where the paramedic on Blackfish got his information from so he wasn't actually lying). The paramedics went to work, attaching a defibrillator, but it was obvious she was gone. A sheet was pulled over her body. Tilikum, who'd been involved in two marine-park deaths in the past, had killed her.
It was this article that Gabriella Cowperthwaite wanted to investigate and in doing so Blackfish was born.
There are probably more videos on you tube if you choose to look for them. These incidents are documented although the early ones are in newspaper archives, the majority are documented by Seaworld themselves. These incidents are all before the movie Blackfish was created, and I hope it gives you some insight into one of the reasons people protest Seaworld regardless of the movie Seaworld like to keep your attention on.
