>>13664552A vomit comet flight is ~90 minutes and a 727 burns ~4000kg of fuel per hour. With that demanding trajectory probably close to 8 tons of kerosene for the flight.
No good propellant mass numbers for New Shepard but its BE-3 generates 490kN of thrust and it looks like it takes off with a TWR of ~1.3. That puts its wet mass at around 40 tons, dry mass is probably 10 tons. So 30 tons of propellant + oxidizer at a 5:1 ratio common for hydrolox would be 5 tons of H2 and 25 tons of O2.
Choosing to ignore that kerosene produces CO2 and hydrolox just emits water, the vomit comet consumes more fuel in its flight than the New Shepard does in its hop. Jeff's joyride is that small
