She's been around for as long as I have, at least the C130A has. Including the Air Force, the National Guard and the Reserves there are more than 500 of them still in service.
There were many versions of the basic design including the C-130 Hercules, EC-130H Compass Call, EC-130J Commando Solo, MC-130E Combat Talon I, MC-130E Combat Talon II, MC-130P Combat Shadow, MC-130W Combat Spear and the WC-130H. There are more I'm sure. The WC-130H can stay airborne for 15 hours collecting weather data.......what a bird
