QUESTION: I would like to know if crewmembers have to undergo any special physical training. Also are there physical requirments for crewmembers (such as height)? Thanks. ANSWER from Steve Patterson on November 15, 1995: To answer your question, I think we need to differentiate between the flight crew and the observatory crew (in the back of the plane). The pilots have to take a special FAA physical exam, with a vision test, every 6 months to maintain their license. All of our pilots are ex-military, and the military does have restrictions on minimum and maximum height for pilots, along with lots of other rules which they had to meet somewhere along the line. For the observatory crew, we don't have any set rules regarding height, vision, or anything else, but the the missions we fly will tax one's endurance, so it helps to be in pretty good overall physical condition. We do have to have periodic physical exams, but they are not as stringent as the ones the pilots take. We also have been through a 2-day high altitude training class with the Air Force, which includes lectures on the effects of high altitude on the body and how to deal with it, as well as a "ride" in the altitude chamber, where they evacuate the chamber to simulate the atmosphere at 35,000 feet and you take your oxygen mask off so you can feel the effects of hypoxia first-hand. They also simulate a rapid decompression of the cabin. The class was very interesting, I enjoyed it a lot. We have to take a "refresher" class every two years, and when we fly above 41,000 feet, everyone on board, including the astronomers, must have this current high-altitude certification. (BTW, there is a test you must pass to get your card.) In addition, we have annual safety training onboard the airplane, where everyone gets to practice using the equipment, opening the emergency exits, inflating the life rafts, and other hands-on activities. Everyone who flys with us must watch the safety training video, and be fitted with an oxygen mask (and learn how to use it). Hope this answers your question.
