As you don't like wikipedia I will come from a different angle.
Before the hearing, Associated Press published an article that said at the hearing a witness would come forward to say that it was the flight attendant who opened the door.This can no longer be viewed on line.
At the hearing passenger Billy Campbell who was sitting in seat 25A said that a panicking female passenger pushed past the crew member and opened the door.
After this a formal apology was made by associated press to the crew member.This can be viewed online using local papers for 9th June 2009.
At the end of the hearing it was said "The highly experienced US Airways flight and cabin crew performed their duties in an admirable fashion."
I am always happy to stand corrected and would be interested to read any information that contradicts this or suggeats that a male passenger was involved.
