I read on https://arstechnica.com/science/2021/06/spacex-to-launch-second-rideshare-pressuring-small-launch-industry/ (mirror 1, mirror 2):
The countdown clock got to T-11 seconds on Tuesday afternoon before SpaceX called a hold to the launch of its Transporter-2 rideshare mission. The scrub was necessitated by a range issue caused by an airplane in the launch zone. The company will now turn around the vehicle for another launch attempt on Wednesday afternoon.
Do space transportation firms such as SpaceX receive a financial compensation in the event that a launch is cancelled because of an airplane entering the launch zone?
