That man who tried to cross the Channel on his jetpack didn't die, but he did suffer a fate perhaps worse: massive public failure. Failure as #1 Google result for his name for all eternity. Failure on the local news.
Even worse, it was an inglorious technical failure like when they can't get a wheel nut undone in an F1 pitstop and even Romain Grosjean overtakes, as the end of Franky Zapata's jetpack crossing attempt came about because he slightly botched the landing on his support vessel when coming in for his halfway point refuelling stop and... fell in the sea. It was a marginal fail akin to forgetting to take the tea bag out of the cup, but one that proved the end of his high-profile sea crossing shot.
A member of his backroom staff was gutted and clearly not impressed by the balls up, and said: "It is a huge disappointment. He must have missed the platform by just a few centimetres. We practiced this manoeuvre dozens of times in heavier seas." [BBC]
