Hm, JATO bottles on an Airbus. Sounds like something "Howling Mad" Murdock would do, along with an improvised sky ramp. I love it when a plan comes together.
It looks like in this video plane was closer to fence than usually and the jet blast may have been stronger than expected normally because of that. Anyway she decided to hang on to a fence despite the warnings so it is entirely her fault she hit that concrete wall.
Besides I don't get what the fuss about this accident. What she did was no more dangerous than riding a MTB on fast downhill track, rock climbing or any other outdoors activity that comes with increased risk.
