context: Early during development of the space shuttle, NASA had estimated that the program would cost $7.45 billion ($43 billion in 2011 dollars, adjusting for inflation) in development/non-recurring costs, and $9.3M ($54M in 2011 dollars) per flight. Early estimates for the cost to deliver payload to low earth orbit were as low as $118 per pound ($260/kg) of payload ($635/lb or $1,400/kg in 2011 dollars), based on marginal or incremental launch costs, and assuming a 65,000 pound (30 000 kg) payload capacity and 50 launches per year. A more realistic projection of 12 flights per year for the 15-year service life combined with the initial development costs would have resulted in a total cost projection for the program of roughly $54 billion (in 2011 dollars).
question: Would the space shuttle cost more in development or per flight?
answer: development
