37,000 FlightAware ADS-B (GZP / LTFG)
that is actual ADSB from one or more LTFG receivers
so it seems ADSB quit at that time at FL370. 9 seconds later disappeared from radar. strange huh
00:26Z 3044 ANTI ICE R WINDOW

00:29Z 2200 AUTO FLT FCU 2 FAULT
00:29Z 2700 F/CTL SEC 3 FAULT
so ACARS first, followed by ADSB failure followed by the radar. I wonder if there is any truth in that 'witness' report about seeing a fireball...
