The Imersat Arc
The imersat track is shown as an Arc if transposed onto a globe does it become a direct great circle track as normally flown? I assume the track was calculated this way. Perhaps they should release the timing data for others to have a look.
Checking with the search aircraft should give a comparison timing.
How many way-points exist in the southern area that can be programmed into the 777 Internal navigation system?
After depressurization is it possible to open the doors and bale out the 777 did any crew have a unusual carry on bag?
