Another scenario - while the crew are preoccupied running through checks and resuscitating the casualty, the rock thrown by the cretin hits the rotor disc or tail rotor which fails on climbout and all aboard are killed (and a few on the ground for good measure).
This idiot "hoodie" in the light blue coat should receive a custodial sentence
for endangering the lives of the helicopter crew and passengers. Alternatively his testicles could be slowly advanced into the rotor disc of a Flymo - that would teach him about the effect of foreign objects on rotors
(or scrota in this case!) This is worse than shining a laser in the pilot's eyes in my opinion (some pond life scumbags were convicted and sent down in the UK recently).
I'm pretty sure the local cops could track this stupid kid down if they wanted to. The CCTV evidence is damning.
Sadly stupid people abound in most countries, not just Holland.
