Flying Boats right when he says read up and be careful !
Working near LGW I have had to give Ambulance Escorts (or Fast Runs as we call them) to a number of people returning from a diving trip and having landed in a very bad way.
We have an understanding with the Ambulance crews......If they turn off their blue lights.....theres no need to hurry anymore ! ! ! ! !
Sad but true.....read up and then be safer than the book says !
ENJOY !!!!!
