Hi FFF,
the firefighters are trained for aircraft accidents.
They work together with other firefighters from other airports and share information.
For the helicopterside it seems, that there is only little information on civilian airports - and thats why they start asking the people, who operate them.
The problem about professional training for them is - where to get it?
On civilian airports there is a wide varity of helicopters coming in for refuelling.
Last couple of days/weeks I recall EC 120, EC 135, EC 145, EC155, Puma, Super Puma, Army Lynx, MD Explorer, A109, Bo 105, Bell 206, Bell 222, Bell 205, Bell 47, Robinsons.....
Greetings Flying Bull
