The FAA issued regulations for space tourism a few days ago, now available on the Federal Register. The security-related section of the regs:
The FAA proposes to require an operator to implement security requirements to prevent any space flight participant from jeopardizing the safety of the flight crew or the public. Security restrictions currently apply to passengers for airlines. Some of the restrictions prohibit a person carrying explosives, firearms, knives, or other weapons from boarding an airplane. Similar types of security restrictions for launch or reentry vehicles would contribute to the safety of the public by preventing a space flight participant from potentially interfering with the flight crewâ€™s operation of the vehicle. Any such interference might jeopardize the flight crewâ€™s ability to protect the public. The FAA notes that one means of satisfying part of this requirement would be for an operator to consult the â€˜â€˜no-flyâ€™â€™ list of the Transportation Security Administration.
If they decide they need “space marshals” too, sign me up.
