brought tears to my eyes..........

truer words were never spoken!!

back to differential air pressure......
this one is from my father who was flying B-25's and such across Texas for awhile for navigator training WWII.
the scene -
across country in B-25 configured for navigator training. Lots of training positions through the tube in back and each one occupied by a navigator student.
so...........
low level, across the Texas plains, in summer. Hot, bumpy, hot, bumpy, more bumpy
students are getting a bit green in back. (did I say it was hot and bumpy?)
the compasses at each position are mounted in a binnacle which forms a very convenient bowl.
(did I happen to mention that it was hot and bumpy?)
student fills the bowl up....
with a little fermentation and some more hot and bumpy, some more bowls get filled up.....
up in the cockpit, bumping right along, the smell is getting a bit "ripe". So the co-pilot reaches up to crack the overhead ditching hatch and let in some air. My father, the PIC, yells out "NO!!!!!" to late....
(recall aerodynamics and areas of low pressure....)
all of the loose papers, checklists, route maps and various "bowl contents" proceed expeditiously up through the tube, into the cockpit and out through the overhead hatch, leaving varying amounts of "residue" on exposed surfaces along the way.
it was a long, long way back to the airfield.......
