I think that since the 9/11 incidents the world of aviation has changed and every airline and government r thinking of ways of how they can increase security percautions. well my idea is this
FINGER PRINT every one who books a flt and cross check there prints with the FBI'/s list of wanted or under suspision list. ITS WAY TOO DAMN EASY TO GET ON A ACFT THESE DAYS AND THIS MUST CHANGE.
If extream measures like these r taken the general public would feel alot safer flying and maybe bring back the business.
