Ok, so 3 out of the last 4 days, I have heard strange aircraft in the sky. It sounds to me like some sort of jet engine braking / acceleration process. Never heard anything like it in my life until now.
Day 1: Silent sky then a very clear sound of a jet engine descending in pitch. The descent sound lasted no more than a second. This is followed by maybe 10 seconds of very normal jet sound. Then the sound wound up in the opposite manner, again lasting no more than a second. Silence after, no fade out of sound at all.
Day 2: Repeat above, but only the initial wind down noise. Sounds slime a normal jet after that and faded out as any normal jet would as it flew away.
Day 3: Nothing.
Day 4 (Today): Didn't hear or notice a wind down sound, but very clearly heard a wind up to silence again.
It's difficult to describe the sound in writing. It sounded like a jet engine rapidly dropping and increasing in rpm. That's the best way I can think to describe it. Never heard it before in my life.
Anyone ever heard something like this before? Any ideas as to what it is?
Pic only ever so slightly related.
