A side note, consider a 747 jet flying from NY to London then back round trip.. approximately 3,500 miles each way. The jet will consume approximately 35,000 gallons of jet A fuel getting 5 gallons per mile. For a trip that would take just over a day.
Now figure how much fuel you have bought in your lifetime so far. Here are some numbers, perhaps your mileage may vary. Consider you own a vehicle that averages 25mpg. You would have to drive about 900,000 miles to burn 35,000 gallons of fuel, total fuel cost $105,000 with a fuel cost of $3/gallon.
Anyone here besides long haul truckers that may have driven that many miles in your personal vehicles?
And, if Jet A costs $4/gallon on average the round trip above would cost $140,000 in just fuel alone!
I complain about putting $40 into the tank filling up...lol.
