Depends on the aircraft, capacity, and form... They range anywhere from $1,000 to $15,000 if new.
It depends on the type of aircraft
You would have to specify a particular aircraft, "fighter aircraft" is too broad a definition.
it depends what aircraft it is and how much fuel it can hold
CO2 is not used in or as an aircraft fuel.
The cost depends on the type of aircraft and the location of the launch. If it's your plane on your field, the cost is only fuel.
15 gallons
35,000 tons of fuel would get you to Paris from London and would cost £4500
The 747-800 aircraft can carry up to 63,034 US gallons or 238,610 L of fuel.
It depends entirely on the type of aircraft and how it is flown.
It depends entirely on the aircraft, type of fuel, how much fuel and where you are in the world. For instance, to fill a Cessna 172 in Canada or US would cost about as much as filling an average minivan, - a 747 would be a bit more - -
it depends on the aircraft. this question is very vague, but the F-16 for instance can hold a few thousand pounds of fuel.
According to some British research, larger airports with a long taxiways like London Heathrow and San-Francisco, can use up to 3% of the total fuel load. For a short-haul round trip, using 5,000kg of fuel, 3% would equate to 150kg or 47 US Gallons of Jet-A. (About $100 worth of fuel).
