QUESTION:
How are the pilots chosen?

ANSWER from Bill Hoss on May 16:
The crewmembers of the KAO are selected from hundreds of 
qualified applicants.  Currently KAO crewmembers all have over 
20 years of flying experience. Most have over 5,000 flying hours in military 
C141 aircraft. In addition to C141 experience, applicants must have flying time
in C130 and DC8 aircraft. In other words, NASA crewmembers are highly
experienced in a variety of jets.  After qualifying each applicant must
complete an extensive subjective appraisal by NASA crew management.  Only the
best applicants are selected.
