Yes, the rules are the same for an air-launched vehicle. From a 2008 paper describing the FAA's approach ("Separation Distances for Rocket Launch Operations" AIAA 2008-7124) the permit applicant must identify and qualitatively characterize the risks of each of the potential hazards associated with its proposed operation and apply mitigation measures ...

Historically range safety has destroyed 2 airlaunched boosters that I know of, the 6th and 9th Pegasus launches. It appears that these were destructed because of obvious loss of control issues rather than corridor breaches though. So: Range safety is a player and will/historically has destruct(ed) air launched vehicles. I do not have the details on the ...

The design constraints for air launch are more about the first stage being able to light while horizontal (no fuel sloshing away from intakes), and the structural additions to support being hung fully laden sideways rather than vertically in the same direction as thrust loads. There also needs to be the flight controls to achieve the pitch up, which may ...

The IRIS launch take off and launch times are (infuriatingly) documented in "local time" at 7:30 and 7:27 respectively (presumably with these events are in different timezones) at spaceflightnow. Spaceflightnow also mentions a 58 minute countdown for AIM . NASA's timeline for the ST-5 mission has takeoff activity ...
