Hey -- isn't that the one that has the amazing changing "N" number? :-)

It seems to me that this movie has one of the biggest aviation gaffes of
all
time, showing a different Cessna on the ground than in the air.

(Or am I remembering a different movie?)

Yep, that's right..

I also remember that the effects with that fuselage were kind of cheesy.. I
didn't know it was a hand made prop till seeing that auction. Watching the
movie I couldn't help but think the prop was digitally superimposed, or
something.
