Oxygen cylinder eyed as cause for Qantas jet hole

---

MANILA, (Philippines), July 27 (agencies): Australian investigators were focusing on the possibility that an oxygen cylinder could have exploded mid-flight on the Qantas jumbo jet that made an emergency landing in the Philippines with a giant hole in its fuselage, officials said Sunday.

Australia's Civil Aviation Safety Authority said Qantas has been ordered to urgently inspect every oxygen bottle aboard its fleet of 30 Boeing 747s.

"At this stage, there is no evidence whatsoever that this is a security-related event," Neville Blyth, senior investigator from the Australian Transport and Safety Bureau, told a news conference. "This is being treated as a safety investigation."
