QUESTION:
What is the age you have to be to get on your plane? 

ANSWER from Curt Laughlin on May 11:
Lots of children come through the plane to see what we have and to get some 
idea of what we do with the flying observatory.  In order to fly on the 
plane, there are no age limits but each person must be there because he or 
she is required in order to do a specific job during the flight.
