I could find no more in the file of official letters mentioning 42A. or any other courses. re hazing There was another series of letters which detail the cost of the Arnold scheme. Originally the Americans wanted $50 Million, made up by 10 for Personnel costs, pay, maintenance & transportation. 32.5 cost of elementary training for 720000 hrs of flying at $45 per hr. 7 for fuel & oil at SFTS, & 1.3 PAA Nav training at Miami. We queried that the Scheme had not applied the Lease/Lend Act and that if something called HR1776 was used the cost reduced to 10 for Personnel, Elementary 7.2 at 10$ per hr, 0 for Fuel, & 0.9 for Nav. Final sentence of the letter to the UK Ministers is we must accept the scheme even if the cost is not below $20 Million.
The thickest File of the four I have seen deals with the official presentation plaques, and letters of thanks to all those who were involved in the Scheme both military & civil.
