Depends on FAA involvement in each launch. In case of an airline FAA controls each flight for hours. In case of a rocket launch, most trouble comes from "don't go in that area" type of commitment, plus investigations of something went wrong.

Given that each airline can keep hundreds of machines in the air at any one time, and rocket launches happen weekly at best, paying 10% of the overall fee does not look fair.

Would be happy to know what aviation specialists think.
