Timeline from the sensors that broadcast during the flight:
To the untrained eyes, the data recorded by Flight 804’s sensors is a meaningless jumble of code and technical language:
00:26Z 3044 ANTI ICE R WINDOW
00:26Z 561200 R SLIDING WINDOW SENSOR
00:26Z 2600 SMOKE LAVATORY SMOKE
00:27Z 2600 AVIONICS SMOKE
00:28Z 561100 R FIXED WINDOW SENSOR
00:29Z 2200 AUTO FLT FCU 2 FAULT
00:29Z 2700 F/CTL SEC 3 FAULT
But to an aviation professional, it tells a terrifying story of a series of cascading faults before the system went dead entirely. I spoke to a European airline pilot who helped make sense of the data from the ACARS (Aircraft Communications Addressing and Reporting System).
The data on its own is far from definitive but the pilot believed “an internal explosion” seemed the most likely cause, explaining both the sudden problems with the windows and the smoke in the cabin. “It looks like the right front and side windows were blown out.
