I'd also like to know what the failure rate is? I was on a flight the other day (B-747) when an oxygen mask dropped by accident in the business class cabin. I was horrified to see that the plastic tubing that connects the mask to the oxygen supply was brownish-colored due to age. I have an aquarium at home, and I know how long it takes for air-tubing to turn brown. While it is quite conceivable that they use a higher grade of tubing in aircraft, that is not awfully reassuring, because low-grade or high-grade, old tubing is old tubing. I shudder to think what condition the rest of the system is in. -goh- ----------------- Speech Research Program, SRI, Menlo Park, CA 94025-3493 USA --- Goh Kawai --- work:(415)859-2231 fax:(415)859-5984 home:(415)323-7214 ----------------- internet: kawai@speech.sri.com radio: n6uok and jk1zyp
