Kindly wave in Austria - or get fired at with signal gun...
 

Hubschrauber mit Signalpistole beschossen - oesterreich.ORF.at

A pensionist fired with a signal gun in the drirection of a starting helicopter.just missing it.
He fired a second round, but by that time the helicopter had enough height.

The later arrested guy said, he had waved and the pilot didn´t respond.....

Greetings Flying Bull

Having worked in Austria I can tell you the people are very friendly... perhaps the pensioner was offended that the pilot didn't wave back, oder?;)

Just because people seem happy and wave to you, doesn't mean they aren't sociopaths :8

The helicopter in question was a government helicopter (police). Pilots radioed to colleagues and the 71 year old idiot has been arrested.

...like the lady who was smiling and laughing when I fell off my bicycle - I forgot to mention it was outside an insane asylum.

About them Austrians
 

Ahm...these Austrians are a bunch of whiners, complainers, and god knows what. Their upper register is sometimes a bit behind the curve, particularly if it comes to matters such as helicopters. "You do something that I am not able to do so I do something to prevent your enjoyment".

Auf gut Deutsch "lieb aber a bisserl deppert":E
