Summary

Licensees must let the Secretary of Transportation put a U.S. government officer, employee, or another person as an observer at places the licensee or its contractor uses. That includes launch and reentry sites, contractor production or assembly sites, non‑federal sites used for crew or astronaut training, and places where a payload is attached to a launch or reentry vehicle. The observer can watch activities when and how the Secretary thinks is reasonable to check license compliance or to carry out duties under sections 50904(c), 50905, and 50906. The licensee must cooperate with the observer. The Secretary may hire someone by contract to do this only if funds for it are provided in advance by an appropriation law.
