Optical illusion or photoshop?


I can't remember if I posted this pic before, if I did I hereby apologize.

But is this real?

Wow! Nice pic! Looks real to me. You mean optical illusion because the aircraft seems to ascend/descend very steep? That is an optical illusion caused by perspective alone.

The red dots blinking at a constant interval reveal everything about the real motion of the aircraft. The real distance between the red dots is constant, assuming constant speed of the aircraft.

The distance, in the picture, between the red dots in the horizontal part of the flight is very small compared to the vertical distance between the dots in the inclined flight. From this you can guestimate the flight angle, which is around 8 degrees. 8 degrees is possible and normal.

Thnx for the explanation, but... The thing I looked at was the distance between the white dots.

It doesn't seem to get a lot wider along the flight path, so it looked to me like the plane crashed ^^
