Well, aside from his not knowing how a turbine engine works, the report
seemed pretty factual and devoid of speculation or exaggeration.

No, this was an older piston engine model. I still don't see how they shut
it down with water and foam except maybe a direct flow into the filter
intake.

Hmmm, so Foam is needed in an airplane fire. Probably takes a specially
equipped and expensive truck, dedicated to airport duty.

Nope. You need the same equipment for auto fires, and for the same reasons. Most
airports count on service from the local fire department if they need it.

and they think irrationally when a woman wears leather clothing?
Because she smells like a new truck.

Yes and no.

It's possible to dispense foam with limited equipment. All you need is
a supply of foam (usually a 5 gallon bucket), an eductor and a charged
hoseline. This is the kind of equipment carried by most structural fire
departments. It takes a while to deploy and is limited in volume of
agent applied.

If the airport is under part 139 (I think it's still 139) then the
trucks will be dedicated crash/rescue vehicles...they will have to be to
meet the specifications. The trucks can arrive quickly at the crash
sight and dispense huge quantities of fire fighting agent very quickly.
Even the "little" crash trucks put out around 1000GPM, the big guys are
closer to 2000GPM.

There is nothing - absolutely nothing - half so much worth doing
as simply messing around with airplanes.

Just to keep the score straight, Part 139 only applies to airports that
serve commercial passenger operations, primarily airlines. Therefore
there is no statutory requirement for a dedicated firefighting resource
at the vast majority of public-use airports.
