I'd return to:
-The first flight (Kitty Hawk, 1903)
-The last Delta L-1011 flight (and be on the flight this time, not told by the reservations agent that the L10s had been retired on 7/17/02!)
-1969, to be able to watch the Apollo 11 landing (on TV)
...or go back to every time I screwed something up & correct it, and relive all of the most enjoyable moments in my life.
I would also go forward, to see whether or not I get married, what job I have, the planes, airports & airlines of the future, etc.
Just my ideas!
Matt D- I've heard of the "Grandfather Paradox" & I thought it was an interesting concept.
