JACKPOT!

Therein lies the solution to why there was a blue million 815s in surplus

Every RUNWAY had at least FOUR or SIX BC-400s in shacks out in boonies...
yet we never
saw any in surplus.  Think Will D once wrote & guessed personally they
were such lead sleds
they just got pitched.

Dweebie note.  All markers worked on 75mcs, only difference was and, still
today,
modulation tone

I remember a ham fella sayin' they still went out & swapped 815s in the
60s.  Only
today did I wonder if they were jamming them in TU-75s.  Could be the
BC-400/TU-75
was the longest continuously-employed boatanchor to come outa ww2!

Using the then-common TU-75 in BC-1158 was a stroke of 1944 re-use genius.

If only a chase plane's BC-1158 had taken over Joe Kennedy JR's B24 (B17?)
a half minute
earlier,   JFK mighta never been pres.

Now there's some MFP'd heritage if ever there was any!
