Biosphere plea

Aformer Biosphere 2 crew member accused of sabotaging the self-contained glass- and-steel dome says she broke windows and opened doors to 'flush' the air for the safety of the volunteers inside, AP reports from Oracle, Arizona.

Abigail Alling told the Los Angeles Times, 'The Biosphere experiment was terminated this morning out of concern for the safety of the Biospherians and the system.' She said she and another former crew member, Mark Van Thillo, had let in outside air. They had been suspended three days earlier in a management shake-up.
