At 18:41 Greg tries to address the pressurisation question by presenting a P-47 flight operation instruction chart. He asserts the tank was "fully tested" to 30,000 feet, apparently only because 'Empty 200-gal belly tank' and '30000' appeared in different places on the same piece of paper. Aside from the difficulty in testing fuel feed from an empty tank, the tank is listed apparently only because it affects performance. It was possible to carry an empty one up to 30,000 ft, but that would be of no help to escort pilots.This video and the validity of its points has already been thoroughly discussed elsewhere on this forum.... I particularly recommend the information dug up by "Drgondog" which come in
on "page" 5 onwards. (see in particular the documents dug up on Hap Arnold, and the stuff on tank pressurisation)
