I recall hearing about a balloon accident on a news programme on TV in the 90s or 2000s. From memory it was some sort of record attempt, and the last telemetry from the flight indicated that the gondola was in free-fall.
I seem to recall a crew of at least two people. I think it happened over the sea, certainly far from where anyone could observe it, hence the need to rely on radio for communication with the crew and telemetry.
At the time of the report it wasn't know exactly what happened or the fate of the crew, but the free-fall telemetry made it sound pretty bad.
Can anyone identify this accident?
