Gulfstream 5 heading this way apparently at 49000' - see they can get up to 51000'... Saw him too, leaving a con trail - suspect that's the highest flying aircraft I've ever seen!
Re the P180, heard it go over while I was in the shower, pretty the last time I went to the RIAT in the 1990s, the ItAF looped one!
Edit: out of interest, would today's extreme temperatures have any significant effect on altitude readouts? I assume ADSB is picking up data from a pressure sensitive altimeter?
