With enough billions, you could easily put several pure-blood pilots and copilots on retainer. Of the myriad of reasons, #1 would be the heart-health of the pilots. Very healthy, high tuned athletes who got the shots and boosters are having major and minor issues. Any ‘fully vaxed’ pilot could easily have a midair incident. Come to think of it, imagine the pilot suddenly dropping out as they try to land a plane.
I can just hear the Unvaxxed pilots calling to the tower “Hello tower, this is Pure-Blood 1 on runway 2-5 requesting clearance for takeoff”
He can use codewords when speaking to passangers.
“We’ll be making a stop in Denver to drop off some cargo.”
The main reason pilots resisted wasn’t as much fear of an accident as the fact that once they failed subsequent physicals their careers were over. Air Force reservists in particular resisted the “vaccine” mandate because they could lose their civilian livelihoods due to side effects/adverse reactions.
