Not so Danny boy.
Evergreen started as a helicopter company, then added fixed wing crafts later on and then got certain Government contracts.
(I was on the payroll over there for 3 years, hauling boxes for Air India, Air France and muslims for Garuda, etc..)
Air America on the other hand was a real CIA invention.
Southern Air Transport was also started to get CIA support in the Carrib and Central America Region, then sold to private hands in,
1972.
