The story
The CIA created BOA in 1964 by using resources from both Air America and Bird & Son. BOA was ostensibly owned by Prince Boun Oum of Laos and was created with the intention of flying missions in Laos with Asian crews (as opposed to Caucasian crews) allegedly for plausible deniability. BOA was based at Savannakhet, Laos.
Due to its high aircraft loss rate, BOA was fully integrated into the CASI by mid-1967 and officially ceased to exist.
