Flew a few time some "Weapon Guidance System" for "some guys" into some "very Oily country". Not too proud of it. The flights were officially done for a famous Big freight company. I initially tought it was just mail and computers. I resigned a few month later after discovering the dirty buisness..
I also had to do some schedule flights into Africa with our Medium size plane fully (to the top) loaded of 200 boxes containing 100 Day old Chikens each...at 3 USD per chiken. We had to be pretty carefull with the pressurisation: their tiny brain seems to be quite sensitive to abrupt changes of Pressure! (60,000 USD of noisy "pressure explosive"small stuff...better be smooth...
).
