Operating a pre-owned Learjet 75 for 200 hours/year costs $908,992, averaging $10.62 per mile. Doubling owner flights to 400 hours/year increases operating budget to $1,422,597 or $8.31 per mile.

The study assessed potential damage a drone impact could cause to critical flight surfaces on aircraft such as a Boeing 737 and Learjet 30/40/50.
