henry, on a Friday night the east part of Glasgow is not really a safe place to land with a police helicopter - even if your landing was safe. The crowd is drunk at that time of the day, and some guys of that crowd had a very frustrating life.. kids have been throwing stones at rescue service vehicles in areas like Glasgow East End..so you have been just chasing these delinquents, would you land on a bad illuminated car park or somewhere completely in the dark if you are not sure its already an absolute emergency?
