Unstable approach:
I consult for a major news network in the USA. You mentioned you had never seen a story improving air safety. We did quite a bit on the "crushable concrete" ( emas) over-runs right after the Southwest Airlines over-run at Chicago Midway airport. I think this story at least sets the agenda to discuss installation of this system. (sadly, I had spoken to a US Congressman,like the house of commons I guess, over 10 years prior to the midway accident and encouraged installation at all airports especially midway, washington national, new york laguardia and San Francisco among others.)
I think as professional pilots we SHOULD speak out and use the media to advance safety concerns.
To the "lady" asking the questions about HELIOS, I have no clue on how to get hold of the "british" pilot on the previous flight.
There certainly is enough information out there about:
1.Easily confusing the warning horn for configuration and high cabin altitude. (remember, by the time it goes off you may already be slightly hypoxic)
Remember that in the simulator, where the pilots are trained to deal with this warning the pressure is sea level or ground level of simulator and the LACK OF OXYGEN at altitude is NOT simulated.
2.Incorrectly configuring the pressurization panel.
I do wish that Boeing and the others would change the high cabin altitude warning to a voice that screams: "OXYGEN.GET ON OXYGEN NOW"
