You have no call to say I'm untruthful.
I said a jet engine would operate on alcohol, You asked for an example. I gave the example of Cooper's flight. It's documented, as I've paraphrased, in David Blume's "Alcohol Can Be A Gas", page 339.
A 1981 article in New Scientist may corroborate that Cooper claimed experience with methanol in a jet aircraft. OSTI.gov's Energy Citations Database includes the article "Can aircraft fly on alcohol" authored by C. Joyce, published Sept 24, 1981 in New Scientist, volume: 91:1272, Pages: 790-793, providing the abstract:
"This article reports on the efforts of Gordon Cooper, a former astronaut, and his partner, William Paynter, to use methanol as an aviation fuel. Methanol supplies about one-half of the kilojoules of conventional hydrocarbon fuels, which means doubling the amount of fuel burnt in an aircraft to produce a given amount of energy. Cooper and Paynter state that at altitude, methanol increases its efficiency and they have reported fuel consumption of 15 litres per hour at 140 km an hour, cruising at over 2100 metres. That compares to about 23 litres/hour with high octane fuel. On take-off and when cruising below 21,000 [sic] metres, petrol still outperformed methanol while Engineers are doubtful of the advantages of using methanol as a jet engine fuel due to its flash point, vapour pressure and its lubricity. Commercial possibilities for methanol as a short-haul fuel are not ruled out."
The abstract refers to both piston driven and turbine driven aircraft.
I see no basis to suggest that turbine engines are incapable of operating on methanol for the flight time from Indy to Houston. Gas turbines, as a class, will operate on broad variety of fuels, not only kerosene. The flight distance is about 865 statute miles, well within the range of the T-38A's nominal range of 1,140 miles (per NASA).
You have suggested, without documentation, that the Cooper flight is a myth, and you have suggested, again without documentation, that Cooper would have added at most 110 gallons rather than topping off.
Your implication is that one of Blume, Paynter, or Cooper fabricated the story. I see no cause to suggest that any of them lacks credibility or integrity.
