That would be a great explanation, if it had been reported that way.
But they did say 'OUT OF FUEL'.
Besides. Why wouldn't the plane burn the 'several hundred pounds of kerosene'?
My gas tank on my car goes right to empty when I run out.
Maybe a few 'ounces' left, but not 'pounds'.
A 737-300 carries something like 30,000 pounds of fuel when fully gassed up. That "several hundred pounds" would be like the half-gallon of gas probably left in your car's tank when the needle passes "E" and the engine quits. I don't think they can suck every drop of fuel out of all three tanks, but I am just guessing.
There's other flammable stuff onboard--oil, hydraulic fluid, some of the plane's fixtures--but I guess they would take a kerosene fire to light off.
