Pegasus rocket, built by Orbital (now from Northrop Grumman) is the first air-to-launch rocket ever developed and still operative.

Maiden launch was in Apr 1990, and last launch, at the moment was Oct 2019. In this frame time 44 launches were performed with 39 successes, 2 partial failures and just 3 failures.

I am looking covers postmarked at KSC, CC, WI or Kwajalein Atoll (Marshall Is) from where airplanes B-52 now L-1011 took place.

Looking for simple covers (postmarks and image as illustration) or signed covers, or whatever space covers involved with Pegasus rockets.
