I doubt you will get many offers on that one.
In flight fuel leak fires... that's something else but I think they tend to be fatal.
Actually my main concern is a LIPO battery in some portable device, say a camera, catching fire This has happened, but I don't think an extinguisher would be much good. I would slow down in level flight, throttle closed, on autopilot, and just before reaching Vs would open the door just enough and chuck the thing out. That's the plan, anyway
