I had the sad duty of responding, during my years in the FDNY to 3 major Air crashes. Lessons learned:
Response takes time due to getting airport Police to escort FD apparatus to the scene if the incident is on the airport taxiways or runways.
Stretching large amounts of Large Diameter Hose is often required, so call alot of help.
Hazardous Material are ALWAYS involved in any serious air crash, and sometimes the cause.
Call more help than you ever think you are going to need. = Multiple Alarms, chances are you will need them all.
Use Foam monitors/Foam lines to protect the pathway into and out of the aircraft, DOORS.
No Foam use large caliber water and handline to stream to protect the pathways & doors to and from the aircraft.
Be aware of injured people laying under any foam blanket, survivors have been run over by crash/rescue vehicles.
Keep the wind at your back, if possible, when approaching the aircraft/scene. Keep track of the direction and velocity of the wind at all times.
Consider the need to rescue victims from the water, most airports are near water.
