    Re: The moons of Jupiter for Time or Position?

    Francis,

    In the early 1970's a C-141 was modified to carry a gyro-stablized 36 in. cassegrain telescope.  Before Hubble and other space telescopes the C-141 could fly above 40,000 ft. for up to 9 hours.  It was owned by NASA and called the Kuiper Airborne Observatory.
