WWII flight lesson
Relearned the hard way! Pilots in WWII did not wear goggles for the wind. They wore them to protect their eyes from other foreign objects that might enter the cockpit in combat: oil, shattered wind screen, shrapnel, etc. Who can forget the scenes from old WWII movies of the pilots pulling down their goggles as they rolled in on the bad guys? Look at the above photo of John Klatt’s canopy exploding when he jettisoned it at the Quad City Airshow. His engine exploded and he had to get rid of the canopy (covered with oil) so he could see to do a dead stick landing (no engine running). Look at the picture below as he shields his eyes from hot oil.
