Here's my take on a news story about French surgeons conducting surgery on a specially fitted out plane that allowed them to simulate zero gravity.
This was done to "advance medical science". The people involved argue that it showed surgery in space is viable (e.g. on a space station). I think they just got really stoned and had a conversation that started:
"Duuuuuuude, you know what would be really awesome? Operating in zero gravity!"
