The demise of the USAF by
Gainis reviews
As a ex Navy person one thing always irritated me about SG1 was having Colonels in command of spaceships, their ships they need a captain! Plus I don't like the USAF, for several reasons, I don't have the space to go into here. (for real) So, I'll just leave it there. So while we are all waiting for wilkins75 this will burn through 5 minutes.
