I am wondering if I heard this. Can't remember if it was Mon 5th or Tue 6th but from bedroom of our house, close to London City (so on a Brize-DET routing), there was a heavy turboprop sound in the distance and up there in the night sky which, not knowing the An22 was coming to the country, I thought might be the aircraft. Can anyone say when it came in and out.
I've seen several in Russia (and have plenty of pics of 09334 in Monino museum near Moscow) but have never seen one on the move. Monino gives you a good chance to examine the huge contra-rotating props on the An22, the Il-114, and the Bear (and one of everything else the Soviets did) at close range. Prime task for the An22 was to carry ICBM parts around the country.
Is the pulsating sound from unsynchronised (or not synchronised very well)propellers ?
