Another perspective is that the Falcon9 carries about as much kerosene as a 747.

  That's a good one, although a 747 gets its oxygen for free.

    Yes, but oxygen's pretty easy to come by it turns out.

    LOX is literally cheaper than dirt (8¢/lb, or 67¢/gallon).

  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. http://www.boeing.com/boeing/commercial/747family/pf/pf_400_prod.page http://www.boeing.com/boeing/commercial/747family/pf/pf_400_... http://www.spacelaunchreport.com/falcon9.html http://www.spacelaunchreport.com/falcon9.html

    Cool, so they're well within an order of magnitude of each other.
