Centaurus,
Thanks a lot for the stories you emailed me, very interesting reading and beautifully written.
Would recommend it to anyone. Have you any more stories ?
A book of your short stories would be marvellous.....!

There was something multi engined pootling around the Luton / Stanstead area about 2 weeks ago around 11:00 - 11:30 at night. The engines / props were not synchronised and the resulting discordant throb was bloody annoying! Far more disturbing than the normal sounds of aircraft in the area.

Quite agree LowNSlow, a few weeks ago a heavy turbine overflew Purley in the wee hours (obviously not the delightful and eagerly anticipated DC-6s!) which had a very bass note and very out of synch... it was aurally quite painful, and that was through double glazing... Don't think it was Herc, certainly not an Antonov (the An-22 can disturb me any time!).

Hercules/C130s have auto synch which works extremely well.
If it was a Herc the auto synch may have been U/S.
In a Lancaster or Lincoln the pilot was able to look through the inner props to the outers. Technique was to juggle RPMs to line up each side then take out the beat between left and right by carefully altering RPM on a pair to synch with the other pair.
Don't remember how I did it in a Beverley.

LnS, it could have been one of our sheds. The auto sync on them very rarely works and some of our pilots seem to have cloth ears!
Like others here, I have heard that the Luftwaffe deliberately de-synched their engines, but from contemporary accounts it does seem as if the HE111 was the worst offender.
