I expect that high performance war planes have little practical use except for war. High maintenance, fuel hungary ect. Great toys when uncle sugar is picking up the tab but sad to say in the post war day they were
so much scrap metal .
Got to think about the way they were designed and built (as fast as possible-after all there was a war to be won)
I had a uncle (since passed)who trained and patroled in flying boats (PBM's?) from may 44 to march 46 .
He was a radioman and was based mosly out of Banana River Naval Air Station.
Key west-Norfolk-Panama-Great Exuma-Gitmo-Galapagos-Puerto Castilla. I have his flight log (747.6 hr)
It just gives the commanders name,plane #, type of flight (training,bombing,navigation,ect) and depature and landing location with total flight time. There are several notes on engine problemns,several single engine landings, one crash landing (no explanation). The whole log is very understated without any extra info. One exclaimation point--"JATO TAKE-OFF WHAT A TIME ! " This was a training flight in dec 1945 when regulations had probably lightened up some.
As a kid I remember hearing him saying he was in the navy as a radio opperator,some good natured fooling around as my father (his brother in law ) was also a radio opperator in the army air corp. I never knew he was in flying boats untill I was helping my aunt move (after he passed ) and found his log and photos of his crew poseing below the nose of this giant plane . What a generation of men !
