Re: misconceptions (physics of flight)



Dear Colleagues,
 
As part of training as a Naval Aviator I took "flight engineering" course at Pensacola 1981.   The recent discussion regarding misconceptions of flight took me to my attic stacks of old texts.  Sure enough,  right under the chapter explaining the physics of flight via the Bernoulli explanation was a diagram that showed two Oxygen atoms being separated -- one to flow over the wing and one to flow under the wing. The text explained that atmospheric Oxygen was, of course, a diatomic molecule and that the leading edge of the wing separated the atoms in the molecule.  To further this lunacy,  the two oxygen atoms were depicted as being attached by springs, apparently to explain that the attraction of the Oxygen atoms for one another grew as they were separated. 
 
Now, we were all a pretty smart group -- in my class several of us had physics or engineering degrees from top-notch schools.  Our instructor was a GA Tech grad.  Alas, none of us challenged these blatant misconceptions.
 
Now all this seems laughable -- I wonder why it didn't then?  Perhaps our inattention was a result of a preoccupation on the abuse du jour being planned by our  Marine DI.   Regardless, when I think of the poor chaps who lives were devastated by being washed out of flight school, I recall Einstein's musing that:.  “It is sad to think of all the science students who were failed for not knowing things we later learned were not true.”
 
Best Regards,
K.
 
P.S.  And to think  we later flew at 400 knots 200 feet off the deck in machines designed by the same folks who wrote the engineering text!   Regardless, it was great to be a "pre-tailhook"  tailhooker -- apparently living in blissful social and scientific ignorance!
