Audio recording of RAF Lancaster under nightfighter attack

Engine noise on aircraft has always been a problem, specifically on combat
(non-passenger) types. On some aircraft, you can tell which position a person
is sitting at by how much engine noise bleeds over to the ICS. Even something
as small as a B-25 has noticeable engine noise and high freq tones bleeding
over when you key the ICS, so I really can't see how a crew aboard a Lanc could
use their normal speaking voices and be heard. As for the technology of
noise-canceling microphones in 1943, I think its implausible that a Lanc would
be fitted with a system equipped with such microphones for every member of the
crew - I agree with the guys who feel this is a studio-done, or
studio-cleaned-up, product. I don't doubt that the dialogue came primarily
from a Lanc crew, but its too clean!

The first thing that popped out at me was the "No Engine Noise" thing.
Again, not only are the engines loud, but they're passing vibrations
into the structure at 2000-3000 Hz (engine revs) and 1000-1500 Hz
(prop revs) each. There should be a bug change in the character of
the background noise when the Flight Engineer pushes the props
up. (Increase RPM) Even with isolated engine mounts, the whole
airplane, and everything/everyone in it will be bucketing away. I
doubt any kind of 1940s recording technology, whether it be disk
(etching grooves in flight - how quiet will that be?) or wire (rare,
and, in fact, it could be that only the Germans had wire or steel tape
(sort of like a bandsaw blade) recorders at that time (Don't tell the
Rootin' Teuton I said so). If the sound were that well isolated, why
do the machnie gunes come through so well?
One last thing - This is supposed to be a Lancaster or Halifax (I
makes no difference for this point) on a night raid. That means that
all the crew would be on Oxygen, and they'd be using the mask
microphones. I don't here anyone breathing. They're talking, I'd
bloody well expect them to be breathing.

Next, I'd like to hear a recording of the Reichsjägerweile - the "running
commentary" radio broadcasts that occurred over Northern Europe during massive
Allied raids. Once the EW stations were overwhelmed, the Lulftwaffe ground
controllers switched to this commentary to tell units where and how the battle
raged - "Many trucks over Dortmund, heading Southward at 7,000 meters; at
fifteen after the hour, Christmas trees and duppel were dropped over Hanover
for what appears to be a feint attack. All aircraft in sector FA are ordered
to land for refueling and await further orders. Pfadfinder reported dropping
flares on Osnabruck in advance of a strong raid..." etc. Hour after hour of
the details of a strike, from the enemy perspective. I think it would be
highly interesting to hear, but as far as I know, there are no recordings
available...?

A combination of a Rugby play-by-play broadcast and the morning
traffic report. But a cleaver colution to the Command and CCOntrol
problem, and, in, some wwys, superior from the OPSEC point of view.
