Early days of Turkish carriers, don't remember exactly which one but 727 IST/LHR. Sat looking at the inside and noticed the galley was not a 727 galley and didn't fit the shape of the cabin! It was a totally different colour as well. There was graffiti on the tray table. Landing was awful with engines throttling up then back constantly and hitting the ground like a lorry load of bricks. Never again!
