One inaccuracy I found is this:

"Under full throttle, a Top Fuel dragster engine consumes 1 1/2 gallons of nitromethane per second; a fully loaded 747 consumes jet fuel at the same rate with 25% less energy being produced"

This doesn't seem right at all, or is at least very misleading.

A top fuel dragster makes about 6,500 hp. Just one jet engine on a 747 produces about 50,000+ hp. It has 4 of these engines. Fully loaded 747's don't fly using only 1 engine. You're looking at 200,000+ hp compared to 6,500 hp.

Maybe the original author got a bit ahead of himself, and posted the fuel consumption rate of only one 747 engine at the economy cruising speed. Because a fully loaded 747 isn't going to get into the air with only 6,500 hp, I'll tell you that much...
