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! Think of what its like in a WWII bomber - you can barely hear yourself think. The drone of those Merlins would be present on the recordings no matter what measures were taken to screen them out - it would be like recording a dialogue aboard the "Maid of the Mist", and somehow screening out the sounds of Niagra Falls, a few feet away. How likely is that? My hunch is that the BBC guys did fly along on the mission, did record it, and brought it back and (at a minimum) cleaned it up before broadcast. 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...? v/r Gordon ====(A+C==== USN SAR Aircrew "Got anything on your radar, SENSO?"

If crew members had to yell over the mics to be heard, then it could not have been a cleaned up recording. The speakers are not yelling. You could filter out the engine sound, but a yelling voice is clearly noticible and no filtration could make it sound like those voices, they were not yelling. If you accept the premise that Lancaster crew members had to yell to be heard over the intercom, it must have been a reenacted scene.

In article , Blair Maynard
writes It could be a genuine recording. Did you know they have actual recordings of Snoopy shooting down the Red Baron during WW1? Yeah, I think it was recorded by a company called the Royal Guardsmen or something.... ![]() Red Guardsmen I think, quite a nice track as well! -- John |

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. I've only just caught up with this thread, so apologies if I'm repeating anything that went before. Breathing: If most of the crew were using their mask switches properly they would only have the mike switch to 'on' immediately prior to talking and would switch them off again when finished, so breathing sounds should be at a minimum (although I seem to pick up one individual who seems to be breathing without talking at times, perhaps WV-T?). Mind you, a WWII era mask tends reflect and thus muffle the voice a bit, and muffling is not very apparent in the recording. However, there is much more that is suspect in this sequence. The pilot is instructed to keep weaving after the navigator has announced half a minute to go before bomb drop, and before the fighter puts in an appearance. If the bomb aimer were staring through the bomb sight stabilisation glass at that time, to get a straight run in on the target, the last thing he would have wanted was a weave. And just who is asking for the weave, and why? Then the pilot is told to steer 'left, left' without having been first told to stop weaving. Then the pilot asks for more revs. Why - just at the time the bomb aimer needs constant speed maintained for his bomb sight predicting computer? This doesn't feel quite right. Then the rear gunner opens up with his four Brownings and amid the noise you can hear an individual gun start and stop cycling. Four Brownings, at a total 80 rounds per second would sound more like a waterfall. Also these shots did not have the timbre of a .303 to me, and although I'll allow that recording circumstances might have made the shots sound funny, what was picking them up? The mask mike of the rear gunner? That might have picked up a muffled roar - and I guess we can assume it would remain switched on in these circumstances so he can instruct the pilot if need be. But would it pick up the crisp cycling gunshots from outside the turret? There would be more clanging from the breeches if anything. Suspicious - but if Gord Beaman can recall the noise a couple of Brownings made in the front turret I will be willing to be corrected. Otherwise - more redolent of a few STENs being fired into a crate in the BBC car park :-) Finally, the pilot is instructed to weave again at a time when the bomber should have been flying straight and level for the post-drop picture to be taken - which would have resulted in a VERY nice piccy of the drop zone. I am sure that Wynford VT really did fly that night and his journalistic skills were put to good use, but this sequence does not add up as a complete real time item. Cheers, Dave -- Dave Eadsforth |

Especially when you recall that no picture meant that the mission didnt count towards the tour total. Keith |
