Orca's are also called Killer Whales and with good reason, stupid human is lucky they were feeling playful instead of hungry
I've not heard of them ever killing humans in the wild and the only example I know of is a bullied male in a sealife centre who lost its marbles and drowned its trainer. Do you have any examples to back this up? I tried googling the origin of the name 'Killer Whale' and it didn't suggest it was due to man eating.
Human behaviour is really interesting to watch. This guy risks being assaulted almost killed at times, just for "recording" people.

has plenty examples of Orcas being murderous to humans, sure there's no documented deaths but it doesn't mean it's not possible, it's like suggesting it's okay to swim in lava because there's been no documented deaths of people swimming in lava, there are some things you know it's better to not do, swimming with killer whales is one of those things
I would love to have this Bladerunner blimp, tho i dread to think how much it must've cost to make.
