Cost of gas for that: Probably $50,000

Awesome!

Compute the cost.. normal low level operations at about 540Knts runs appx
36,000pph (that's pounds per hour fuel flow for those not used to jet
engines), I used to plan at 38,000pph average to allow slower times and high
speed dashes.

One gallon of JP8 weighs appx 6.5 pounds (rounded), that's 5540 gallons per
hour (rounded), at a buckfifty / gal that's $8,310 per hour (rounded). The
apx 5 minute run, ok, I'll give him 10 minutes on the run, $1385.

But that's at 540Knt or about .88M depending on altitude, rack that up to
Full Afterburner and greater than 1.0M and the fuel flow meter is off the
scale. But rack the pph up to 100,000pph and the math still works out to
less than $4000 for fuel.

Now, add in the cost of crew training, aircraft maintenance and investment
in the airframe. And it does start adding up.
