Weird noise from sky

    Not strictly weather related but just had a very strange experience here.

    For the last 10 minutes, and very deep 'droning' sound was heard outside, so deep in fact, that the chair I was sitting on vibrated. Went outside, as did others in the street, and the sound clearly was coming from the sky, but such was the nature of the sound, it was hard to pinpoint a specific point. The sound itself was constant, but the deeper sounds came in specific 'waves'. I am sorry I wasn't quick thinking enough to record it but it was very weird and very very eerie.

    Anyone any ideas? Is the current state of the atmosphere making the sound of ordinary jets sound stranger than they normally would be? or have the Russians decided to go all out?? :eek: I jest of course but this was no normal aircraft sound.

    It’s an AN22 routing Gander to Man

    The red and white Air Sea Rescue helicopter flew low by here on a wet and windy day last year and sounded exactly like that
    It was heading for to airlift a patient from a crash on the nearby motorway

    Know that sound well BB, as those helicopters fly over here fairly regularly, and indeed produce a very ominous sound as they approach, but this was something way way bigger.

    To the previous poster. Looked that plane up just now, massive yoke. Was it due to fly over the west of Ireland tonight? Those destination codes I just can't fathom out. :o

    Gander is in Newfoundland, Canada, Man is Manchester.

    Route of that Antonov An-22 from flight radar:

    Flew almost directly overhead, but Christ, it must be one fast plane considering that it is now coming into Manchester!

    Cheers Alun, eventually worked it out from Flight Radar.

    Yes it flew over here last week heading to Cuba from Manchester I think. It’s the largest turboprop aircraft in the world. Apologies for not explaining where those places are!

    I think I heard it too in skerries, deep droning sound around that time, wondered what it was


  • Registered Users Posts: 15,314 ✭✭✭✭ Discodog


    The Antonov An-22 "Antei (NATO reporting name "Cock") :pac:

    Relieved that it was of a benign source. Had it in mind that maybe something more sinister was going on given the developments in the M.E today. :cool:

    Crap, I was hoping it was Aliens.


  • Registered Users Posts: 6,033 ✭✭✭ Oneiric 3


    Sound was something like this alright, only 'dronier' and wavier.

    What a colossal beast of a machine really.



    The fact that it caused vibrations even in the house is amazing.

    Up close with the AN-22, note the flames from the engine on start up



  • Registered Users Posts: 14,307 ✭✭✭✭ nacho libre


    I think the obvious answer is it was in fact Ailens, but when they saw what a kip Tuam is they decided to head back into space:P

    what are the main benefits of prop planes over jets?


  • Registered Users Posts: 9,393 ✭✭✭ Oscar Bravo


    When speed isnt a factor, eg that AN 22 was used to bring an engine for an a330,the main reason for preferring turboprop engines over pure jet engines is that turboprop engines deliver more power and greater efficiency at slower flying speeds than jet propulsion.
    The AN-22 that passed over earlier has the capability to takeoff from rough and short airstrips, this is achieved by four pairs of contra-rotating propellers. The engines generate significant thrust, and produce a slipstream over the wings and large double-slotted flaps.

    Crap, I was hoping it was Aliens.

    To be fair the red top tabloids have been running 'booms in the sky' stories over the last few weeks, occurring around the world.

    741 mph sonic booms or some sort of ionic skyquakes?

    There was a few meteorites/fireballs burning up recently, but nothing of any sizeable note...

    If it is aliens someone should probably call Will Smith seeing as he has so much experience in saving us from aliens

    Inside the back of the one that flew over this evening upon arrival at Manchester, massive!

    I posted about it in the aviation forum when it passed over me here in north Dublin. At the time it was flying at 27,000ft with an indicated airspeed of 380knots. The drone went in for nearly 10minutes and came and went in waves. I'd have liked to have seen it from the ground but darkness and cloud put paid to it. The bulk of the noise stems from the fact that - as Oscar Bravo put it above - it uses contra rotating propellers on each engine. Russian props are not quiet at the best of times but this particular machine takes noise to new levels. The Russian airforce still uses a number of large "legacy" propeller powered aircraft and all have the same predisposition to making lots of noise! (Google Tupelov 95 and see what I mean :) )

    Its ground speed was around 370 knots, and that was with around a 50-knot tailwind at its cruising level of FL270. Much slower than say a Ryanair 737, which would be doing around 500 knots at the same level.

    She's some machine alright, with her alternating double props generating that low-frequency hum. But she's nothing compared to her big cousin, the An-225 (Mriya).

    I too heard this over head this evening here in the midlands... I checked flightradar to find it the Antonov AN-22 as others have mentioned.

    Wonder why its making so many trips to Manchester lately?

    I see it used for moving military machinery.... someone getting new equipment i wonder

    Why am I not surprised that aviation and meteorology are mutual interests among many !:)

    Another weird plane sound droning from the dark skies here at the mo. Looked on 'Flight Radar' and it is a similar, if smaller plane what caused the freaky sound that prompted me to open this thread last winter.

    People in the midlands and east should hear something weird soon as the 'Antonov An-12BK flies over soon. Still droning away here even though plane is well over the midlands by now.
