[ARC5] YG,ZB question or two

[Tom Clarke]

I flew a test project out of Andoya Norway a few years ago flight 
testing the (then)
  new Ring Laser Gyro Inertials with embedded GPS in both the C-130 and P-3.

Part of the test was to dump the INS and see if we could get an inflight 
alignment
above 85 North.  It worked !

Can't agree more on the Northern Lights!  It is a bit strange to be at 
the NP and to
see the Aurora overhead and to the south. Made HF comms with Bodo Control
  a bit "watery". Of course, everything is "south of the NP!
