11,000 gallons of jetfuel weighs about 77,000 lbs. You claim Flight 11 only took off with 20,000lbs of fuel and you somehow think 20,000 is more than 77,000!

If you had been paying more attention, you might have caught the actual error. A claimed 20,000 lbs would not only be less fuel than was stated in the image, it wouldn't have been nearly enough to get the jet from Boston to LA. I just swapped gallons and lbs in my head without thinking about it. It was supposed to be 20,000 gallons, which was wrong, but for a different reason.

The numbers I found online for a 767-200 claimed United used about 16,000 gallons on an average trip between NYC and LA. Since Boston is slightly further, I estimated 18,000 and went from there. However, I was doing the math in my head last night, and I realized that works out to about 40MPG per passenger, when I know the figure for a jet like this should be in the 70+ range. Turns out that figure is for a round-trip flight, so I was off by a factor of 2. The actual number is closer to 10,000 gallons for Flight 11 alone.

Diesel fuel! LMAO! Jets burn kerosene, Einstein!

The fact that you wrote this "dunk" not knowing that diesel fuel and kerosene are the same thing gave me a good chuckle. Diesel fuel, kerosene, and A1 jet fuel are all basically the same chemically. You can pour A1, or straight kerosene, into your diesel's tank and it'll run, though for lubrication you'll also want to add a pint of 2-cycle oil to every 5 gallons of kerosene if you want to do that long-term.
