American 767 RTO at ORD

That's just got to be a nightmare for CFR when there's people wandering around taking selfies on the surface.

It is. You can see in the video taken, the one CFR truck that has to come to a halt as it's trying to go around the left side of the jet to go around the nose for a front quarter foam attack. All because of people milling about. The only people who should still be there, are the ones at the bottom of the slides still assisting egressing passengers.

CFR likely has to take more time getting to the aircraft because of running someone over at SFO when Asiana stacked the 777. This will just make it worse...

That was moreso being more careful maneuvering around foam covered ground. The problem being people you potentially can't see, vice people milling about that you can see. Granted, each will cause you to slow down.

Wasn't there some protocol suggested like using the thermal camera to see people in the foam? I didn't follow the developments but I remember reading something about it.

Can try, but it's not really optimal for that (assuming its installed). Because you're pointing at the aircraft, and fire on the aircraft will create an image of far more thermal intensity, thus washing out any kind of little heat a human body gives off. Plus, the camera is generally on trucks with a snozzle or HRET (High Reach Extendable Turret.....boom attachment) and located at the end of the boom, so the elevated boom is not looking down at the ground, since the nozzle itself isn't looking at the ground, it's looking at the aircraft and where the foam is shooting. Non snozzle-equipped trucks generally won't have a mounted thermal image camera installed.

That said, a thermal image camera isn't very useful in a fully raging fire. It's sole purpose is to find areas of heat/fire in places where you can't see fire. Such as inside a cargo area when you are outside the aircraft and can't see active fire. Any fully involved aircraft, the thermal image is just a blob of washed out heat imagery.

I hear the pilots are dropping an album. :)

Thanks MikeD it's great having someone knowledgeable about this kinda stuff here

So on this Snozzle, you have your piercing nozzle for punching through the fuselage and fighting interior fire (ironically, first ever used during the Fedex 647 crash at MEM in 2003), a coaxial fog nozzle, a floodlight, and a thermal camera. You can see that being on top of the truck, and pointing where the nozzle would be pointing during a fire (its pointing down only in the stowed position), you're not going to see anything on the ground. And if there's a fully involved fire, the thermal camera screen will be mostly washed out by the intense heat.......which, since you can with the huge fire in front of you.....makes the thermal camera unnecessary in that situation.
