Faith - a definition!!
NMPKT (Not Many People Know This)
But in the late '70s we were patrolling the skies above London in a G5A and then a G3B1 on contract to the Met Police. I have a great snap taken overhead Big Ben at 200 feet whilst policing a protest march - taken through the bottom of the bubble.
Those were the days!
Heaven knows what would have happened if the donkey decided to wrap its hand in.
On one occasion an illegal Heathrow overflight by a light FW caused a panic and we were asked to chase it. The ripples of laughter cause a temporary loss of decorum. With a Vmax of 90 knots we weren't going to chase very much. Even traffic pursuits were challenging, especially into wind.
The best tip I can suggest is chose your police observer carefully - two of you over 6'4" and life gets to be 'interesting'.
