80% accuracy is unacceptable for a deaf or hearing impaired person to use. It really needs to be 95-98% or so for a good understanding of the entire thing.
I decided to fact check you. 57,285 U.S. gallons in a fully loaded 747. Jet-A is 6.84 lb/US gal. That's about 196 tons. Looks like stage 1 of the Falcon 9 is estimated to use 239 tons of RP-1 and stage 2 49 tons.
