A few years ago one of the top UK news presenters (can't remember who) wanted to feature a "good news" bulletin once a week. His idea was turned down flat by the TV company as they said nobody would watch it. They were probably correct. Nobody seems interested in good news.

What aircraft is it? (i forget to read the link). Nothing like the Helios 737 crash anyway. I think the cause is a fauly Oxygen recycler (i don't if airliners have oxygen recycler. Or maybe the same problem in the Helios 737).
 
In the memory of 121 people in the Helios Crash. RIP

Oh yeah another 737. Blame Honeywell! (the company who manufactures oxygen systems on 737's)

Blame Honeywell?
That's rubbish, blame the maintenance responsible for keeping the aicrafts in flying condition.  Undecided

There's very little doubt that Honeywell is a top notch supplier to the 737 family, ranging from wheelbrakes, to APU and the CDS, so get of their backs.

I guess that is true. Probably loads of aircraft have failures of one kind or another everyday.
Nevertheless, it is interesting that it was the same breed of aircraft.  Roll Eyes

Now i'm scared to be on 737's. I should stick to A320's and other single aisle airliners. But i still blame Honywell!

Working on that basis you would blame the manufacturers for anything that goes wrong. Fortunately in this case the emergency oxygen system worked properly & the aircraft was landed safely. Something apparently went wrong with the emergency oxygen in the Helios incident. The cause will probably be found in due course but it's quite possible that someone forgot to replace the oxygen supply or didn't connect it properly. This is only an example but I don't see how you could blame the manufacturer for something like that. It's also quite possible that the emergency oxygen system used on the Boeing & Airbus is manufactured by the same company & not Honeywell. http://www.cobham.com/news.asp?pageID=128&menuID=2_4_2&articleID=26&type=archive

Carleton Technologies Orchard Park

The hub of the Carleton family is in Orchard Park, New York. Home to over 250 employees, the operation still counts among its active members one of the original founders of the company. The roots of the company's technology lie in regulating high pressure oxygen to breathing levels and this capability won a position on the first US manned orbital space mission. Since then every US astronaut has depended on using Carleton's sophisticated and extremely reliable breathing equipment.

Over the years, the company extended its technologies to encompass high pressure gas storage and regulation for pneumatic control systems. Included among its customers are the US Military Services, Lockheed Martin, Raytheon, Boeing, Hamilton Sundstrand and many others. Its products are widely used throughout the aerospace and defence community. Typical applications are for missile control (Paveway Laser Guided Bomb, Joint Air to Surface Standoff Missile, Javelin), aircraft emergency equipment (V-22 and Comanche landing gear release) and emergency oxygen systems for all Boeing's7XX aircraft and for the Airbus A340 and A380.

I could be quite wrong but I always thought the emergency oxygen in the cockpit was completely separate from the cabin supply. It should be easy enough to provide the flight crew with self-contained emergency bottles like the B-17 crews used in WWII. This would give them time to make a rapid descent if pressurisation is lost.

Funny Doug I thought the same thing. I thought there was an independent circuit and supply for the cockpit....
I think Nexus is right that the service records and individuals need to be looked at, mind you as the saying goes "If you pay peanuts expect to employ monkeys..." Roll Eyes
I have a funny feeling Helios will v.soon be out of business, one or two others are probably also borderline.

Personal emergency oxygen systems are readily available. Maybe every airline pilot should carry one in their flight bag. http://www.avweb.com/news/aeromed/182584-1.html

One little snag is that oxygen is treated as hazardous cargo. Not sure if that would comply with the regulations. Roll Eyes

oxygen is classified as a Class 2 Hazardous Material, and federal hazmat regulations prohibit the shipment of filled oxygen cylinders by air -- even if they're tiny palm-sized 18-liter cylinders.

My bottom is classed as hazardous cargo (after a curry at any rate) and they haul it Grin
I think they'll have to look at some option like this...
