Up to this direction from the Kennedy Administration MATS had only required troop carrier units equipped with C-124 Globemaster II aircraft to be qualified in its Computed Air Release Point (CARP) aerial delivery technique. The CARP technique required the aircrew to file a detailed flight plan detailing the route along with the exact Time on Target (TOT). Using the CARP process correctly would ensure that an airdrop would be made based on time and would allow the airdrop to take place even if the at night or if the drop zone was obscured by weather. Beginning in January 1961, however, MATS required all C-124 units to become CARP qualified.
