A G-1 is probably the least appropriate aircraft for his list.
.
Great old aircraft, but they like fuel, and they would do the mission with ease.
true story, (A G-1 in the military is known as a TC-4C it was a A6 bomber trainer) We overnighted at Nellis AFB and the next morning we pack a full load of JP-5 and took off for home, midway home our APU quit. (that is where we got heat and air-conditioning) so we plodded along with no heat, after we landed whidbey, we gripped the APU.
the next day we found the APU fuel filter full of water as was the fuel control for the APU, and all the fuel lines to it.
We tried to sump the main wing tanks and couldn't because of the amount of water frozen at the bottom of the wing tanks. We put it in the heated hangar and over the next few days we dumped over 150 gallons of water from the main tanks. The ice crystal formed in the fuel would come down the main engine fuel lines hit the fuel heaters and melt, and be fed to the R/R Darts and their fuel controls would feed the fuel required to get the power needed to continue to fly.
We bore scoped the hot sections and those were the cleanest engines I ever saw, those old Darts steam cleaned them selves all the way home.
I liked the G-1, it's bullet proof, you can fly that aircraft with all the electrical circuits off and no hydraulic power. all flight controls were cable driven, and all engine controls were direct linkage.
All 9 of the TC-4Cs had in excess go 50,000 cycles when the Navy ended the A6 program.
