Deflated???
 

How many pilots out there have suffered a collapsed lung? It can happen all on its own and flying is not advised at all. I just wanted to know (as someone who has had a lung go south) if there is any hope of me being a pilot?

Yeah, I know a couple of guys that have had a lung collapse. They are flying just fine.
(Oz ATPL)

Know of one who had that happend more than once - he is flying with a scandinavian ATPL.

......the hard part is staying still while i stick a chest tube in you !
