PITTSBURGH, Pennsylvania (CNN) -- An expert said Wednesday that oxygengenerator bottles should be safe to ship as cargo, but admitted they heat up to 1200 degrees inside the canister when activated.
The NTSB released documents Monday showing that employees of SabreTech told investigators that the oxygengenerator canisters were sitting around a stockroom at SabreTech in Miami when a stock clerk decided to gather them up and send them back to ValuJet in Atlanta.
