Charlie Robb says:
Len Airey talks in his excellent book "On Antarctica" about finding and skiing with it at Faraday and then taking it to Halley - must have been 1984. It unintentionally departed Halley roughly in the direction of Faraday with a sledge unit on Sunday 20th September 1992. Whoops.

The parachute was on base in 1970 - idea was it would help pull a sledge but it had apparently never worked and nobody was really bothered with the thing which regularly deflated right in the track of the sledge and stopped it.

[Presumably a different parachute from the one mentioned by Charlie -- Ed.]
