2 years ago, I hit a bird in an A320 and I felt the impact. Very slight, but felt it. Also heard it and even smelt it(bird went through the engine).
A wing hitting another aircraft.......
Lets take a gull, say 1kg, travelling at 400kt = 205m/s
Kinetic energy is = 1/2mv^2
Which for the gull would be 0.5 x 1 x 205 ^2 = 21, 012 Joules.
The lamp post is not so clear as we dont know its exact mass in the horizontal move, but lets say it was 100kg, being accelerated up to the speed of the taxiing a/c, lets say 15kt = 7m/s
Kinetic energy = 2450 joules
The lamp post imparts approx 1/10th of the energy that the bird does.
