My grandson did a course there a few weeks ago and enjoyed it, he's only 13 but he wants to be a fireman
When I was in the army working down south we used to see the Navy training fleet auxiliaries crew (mostly Chinese) in tackling Helicopter fires, they had a mock up of a chopper made of steel pipe, they stuck the crew into silver flame proof suits sent them into the chopper and set fire to 10 gallons petrol, terrified me not sure about the crew.
