What a load of tosh. The police do have aeroplanes, despite being cheaper, they still go for the expensive helicopter. I wonder why? Oh, and planes don't crash of course, or make the crew spew flying round in circles, or make small adjustments to see down the side of sheds, or look straight down when needed, or land and make arrests, or operate away from airfields, or land and pick up casualties when needed, or zzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzz
