747SP Telescope Platform

Mon Oct 16, 2000 8:17 am

Check out this fascinating re-use of a 747SP:

Any of you list junkies out there know the provenance of this particular aircraft? Also, any links to more detailed information on the 'Net?

Thought y'all'd like to see this one.

Sofia is the next major airborne observatory. It is a former Pan Am/United 747SP. I believe it is in storage right now at Marana... though it could have been moved.

My boss, was in charge of the old Kupier Airborne Observatory, a joint venture between NASA and the University of Arizona Lunar and Planetary Lab. They fitted a small, 2-meter (?), telescope with a spectrometer and all the related gadgetry into the prototype Lockheed C-141. This was all based from Moffet. Before they had the C-141 they used two CV-990s (one crashed) and several LearJets. The C-141 was decommissioned in 1990 I believe and nothing has been doing that sort of work since then.

The 747SP being used for the SOFIA program is N145UA (ex-N536PA).

The fuselage of sister N141UA (ex-N531PA), scrapped at Ardmore OK, was used for testing/modelling how the telescope would be fitted.
