While HALPRO might have trained in the same location as the 98th BG, it was it's own seperate entity.They were 23 hand-selected crews, the best of the best at the time, trained for a specific mission: to set up in China and conduct virtually suicidal raids against the Japanese.
HALPRO was later joined in late June 1942 by a detachment of 9 B-17 aircraft from bases in India. With the addition of the B-17's, this group, a total of 32 bombers with their support crews, became the entire U.S. Army Middle East Air Force, called the 1st Provisional Bomb Group.By August other a/c units were in the process of being transported to the Middle East, in preparation for the introduction of American combat ground troops into the theatre under Operation TORCH.
As these newly arrived aircraft became operational, the 376th Bomb Group was constituted and activated in Palestine in October 1942. HALPRO was assigned to this Group as a more rigid and organized command structure began to evolve.
So where are the records?Flight records, load lists, personnel records, etc. typically stayed with the group, so my educated guess is that they eventually became part of the 376th BG records. Considering this was such a specialized unit, the AF Historical Research Agency might have seperate files on HALPRO or the 1st Provisional Bomb Group. Another remote possibility is that since HALPRO flew in support of and along side of the British Western Desert Air Force, the Brits might have some operational records as well.
