I can definitely testify to the wing tip locations of the older 747s. In 1990, aboard Clipper Black Sea (N743PA), on a max weight takeoff on a hot day from FRA
, we had to jettison for 30 minutes after #1 failed. What a stomach in throat feeling when after a minute and a half takeoff roll (I usually seen 1 minute), there is a loud bang just after rotation,followed by a nose down motion too close to the treetops.The flight attendant I was seated next to at L4
told me "we're not climbing" and I told her " atleast we're ABOVE the trees! ". Thanks to Boeing and the crew up front we were able to eventually make an uneventful landing. And to think I asked the captain before takeoff if I could ride up there with them instead of having to wait until the next flight!I wonder to this day what that would have been like!
