Hrm. Imagine living near to the flight path of an airport. Say something like 1.5km to the side of it, at which point they are about 400m high, going between 280 to 320kph, depending on the wind, and model.

One late evening, shortly before 23:00, where airport is closing for the night because of local noise restriction laws, except for emergencies, otherwise heavy fines, something wasn't on that glidepath.

Immersing me in it's landing lights from beneath, and somewhere in the middle from each wing. Flew erratically. Curve to the left and coming down really low, then UP, then going back right towards the normal path. Coming directly over me.

While doing that the wingtips vibrated by at least half a meter, making the position lights a blurred vertical line. Wasn't even that loud, just BIG!

If it wouldn't have done the reclimb and curving back towards the path, it would have crashed into the highrises next to me.

What was it? A 747 from UPS, clearly visible because the golden letters against the brown tail were illuminated.

Sat there at my desk, thinking WTF?! Are you doing VFR, or what?
