You would have more pilots if you didn’t force them to take the clot shot.
The clot shot was kinda the final nail in the coffin. The pilot shortage has been coming on for years. The main reason is because flight training has become so expensive. Why? Tort mostly. Our litigious society is costing us dearly. There’s an A&P mechanic and IA (certified inspector) shortage, too, much for the same reasons. Airplanes come and airplanes go, but signatures in logbooks last forever. Add it all up, throw in some DEI, and it doesn’t bode well for commercial air travel over the coming years.
