This may help explain the environment during the WWII time frame with govt/defense contractors. My reading of this leads me to believe it was a three-fold purpose. One of course was rooting out the fraud, waste and abuse in govt contracts during the war. The others were political in nature dealing with protecting FDR's lack of oversight and excessive spending and greasing the skids for Truman as the next President. I Googled around for Martin aircraft issues involved with the Truman Committee. I seen the frequent B-26 crashes mentioned a few times.
https://en.wikipedia.org/wiki/Truman_CommitteeI read this about the R-2600's built at that Curtiss-Wright plant. That is where I got the idea this was the engine the subcommittee report was talking about. Someone else may know more about this and if any other aircraft engine types were involved??
http://www.enginehistory.org/Wright/R-2600/R-2600Lockland.shtmlYes, the Navy's decision not to embrace helo's early on was surprising. I knew the AAF and USCG were deeply interested in the use of helos....the CG more for SAR than ASW and I believe the AAF for field medivacs of the wounded.
We were having an offline discussion about the CG's three Curtiss SOC-4's (V171, V172, V173). One of our CG aircraft historians mentioned he located in his research that after the Truman Committee's work, future VP and Prez Truman made sure Curtiss did not get anymore govt aircraft contracts, which was their demise for aircraft production. He also mentioned the govt/AAF told them to start producing P-51's and they refused and kept producing the P-40. There may be more to the story but that was what he was recalling.
