STS-36 (Atlantis)

 1990-019A

---

Atlantis flight 6 was another classified military mission. The short flight entered the highest inclination orbit ever achieved by a Shuttle, 62 degrees. Normally, launches from Cape Canaveral are restricted to at most 57 degrees inclination to avoid passing too close to the US East Coast. It is believed that the main payload was a TRW/Lockheed Improved CRYSTAL (modified KH-11) imaging reconnaissance satellite.
