Weird looking object -- was it ever a real aircraft? And, the front
part of the fuselage looks so oversized, like a Super Guppy -- or is it
maybe just a short stubby section chopped out of a much larger aircraft?

Thanks for info.

It is made of fairly thick steel. They use some kind of fuel to catch it
all on fire, depending what they want to practice, then spray out the fire,
and enter the fuselage, when desired.

There was a similar ship in Alice Springs. We were standing on the ramp
there when they came and torched it off and then had the trucks come
running up and put it out.
