On  April 20-21, 1964 or nearly ten years after the first flight of the Lockheed YC-130 Hercules prototype, the Lockheed Model 382, serial number 3946, the commercial version of the military C-130E, made the longest first flight in history when it flew for 25 hours, 1 minute, after taking off from Marietta, Georgia (USA). The aircraft was certified by the US Federal Aviation Administration February 16, 1965.

The L-382 was powered by four Allison 501-D22 turboprop engines, rated at 3,755 shaft horsepower, and driving four-bladed constant-speed, reversible-pitch propellers.

N1130E was retained by Lockheed as a demonstrator, however it was briefly leased to Alaska Airlines, in March 1965, and returned the following month.

The L-382 was converted to the -20 standard in April 1968, with a 5 foot, 0 inch (1.524 meters) segment added to the fuselage behind the cockpit, and a 3 foot, 4 inch (1.016 meter) section behind the wing.

N1130E was leased to Delta Air Lines in October 1968, and returned after six months.

Lockheed sold N1130E to Pepsico Airlease Corporation, who leased the freighter to Flying W Airways. It was reregistered as N50FW. In March 1973 Pepsico sold it to Philippine Aerotransport and it was operated for the Philippine government, first as PI-97, and then RP-97.

After sixty-two years, the Lockheed Hercules remains in production, and both military and civil versions are in service worldwide.
