As a science teacher and a licensed pilot, I really appreciate your
debunking of the "facts" about air rejoining as it travels over and
under an airplane wing. I try to teach science 'truth' in my classroom
but often find textbooks are in error, perpetrating the same half-truths
and no-truths for decade after decade. I made students shoot two
differently colored jets of air over and under a wing shape and they
quickly came to the correct conclusion, the airstreams do not meet
A simple question to my students began the wing experimentation; :"If
the shape of an aircraft wing... pulls it up... , why doesn't an
airplane fly into the ground when inverted....(Smile)
