The sound engineer was Reg Pidsey and he used disc

The lack of engine noise is rather odd. One would expect anybody trying to
fake such a recording would be quite capable of adding it.


Unless of course the intent was to subtract it to make the
soundtrack audible.

It is obvious that people talk over each other, so either they are all in
the same room, or they have a full duplex system. Actually, it sounded
like
they all had open mics. We don't hear much in the way of non-vocal noises
other than the machinegun bursts. Presumably that burst was picked up by a
mic which was open although nobody was speaking, so there had to be at
least
one open mic, since they didn't have voice-activated mics back then.


Or the crew were recorded using a second non-standard microphone

Some of these things may be explicable. We would need to know the location
and recording characteristics of the recording device and how it was
hooked
up to the comm system of the aircraft. And information about the comm
system
of this aircraft to see if such a conversation was even possible. The
nature
of the device could explain why the engine noise didn't get recorded.
Early
recorders were probably not very good at recording low frequency sounds.
It
may also explain why the machine gun sounds so tinny.


The equipment used was apparently restricted to the range
60 Hz to 4500 Hz

I don't think the crew was incredibly calm in that situation. They are
flying
