Strange sounding AC @NCL
Sitting in Tynemouth at about 1250PM Friday. aircraft make their approach up the coast before turning into NCL runway.
I heard what sounded like a helicopter in the distance getting closer - quite a distinctive "clatter" Dismissed it as the police chopper or whatever but when it got closer the sound got deeper and evolved into a turbo prop.
Couldn't see it from where I was. Obviously we get a lot of turbo prop twin engined stuff over hear, but I've never heard anything like that.
What was it?
Thanks,
Tyne
