These are the big boys!
C-141B, Kathy:
The hump above and behind the flight deck is for Mid-Air Refueling. The 141 is much more labor intensive than the C-130 (Which is one of the simplest, most reliable planes in the Military) And not all that much faster than the Herk.
141s are being slowly phased out and used mostly for MedEvac right now. You can set up the inside of the plane for up to 70 Litter patients. Lots of electrical outlets for de-fibrulators, incubators, crash carts, EKGs and EEGs.
The AF played around with the idea of using the 141 for LAPES. It's longer and wider, but its engines are not as quickly responsive as a C-130. With a higher risk of stalling after letting the cargo go and pulling up and away.
Jack.
