would require 10 aircraft be constructed. WIth two spares used as
training and test aircraft, that's 12 aircraft. At $200 million per
aircraft, this is a program cost of $2.4 billion. With 12,000 flight
cycles per aircraft, this is a total of 120,000 flight cycles for the
10 operating aircraft. With 450 passenger seats at 75% loading - 338
passengers per flight. 40.56 million trips per fleet. At 2 flight
cycles per aircraft per day - that's 12 year life span. At $450 per
flight that's a $300 profit per trip - or $12.2 billion profit for the
fleet. The flight consumes 7.44 million tonnes of hydrogen over their
lives.

Increasing costs to $750 per flight and assuming a loading factor of
85% - dramatically increases profits 226% to $27.7 billion over the
life cycle of the fleet!

If development costs can be kept to $10B that Boeing is variously
reported to have spent to develop the 777, the price of the 10 aircraft
jump from $200M to $1200M. How does that affect the business plan?
