Ridiculous indeed! Living near YVR and flying out of there many times, I'll never forget what happened more than 20 years ago:

Surely this matter is sub judice. Articles like this cannot help justice for the accused. After all whether we agree with them or not the accused are entitled to a fair trial.

Out of those initially arrested around a year ago, how many are in trial right now or have been convicted since last summer?

Chertoff is free to run his mouth in the US and have journalists peddle that. Also, weren't nearly all of those arrested on this matter beyond the US? If people outside the US were to take everything Chertoff says and does seriously, I would hold their judgment to be suspect.

Not compelety true. Some aircraft do a small pressure differential before t/o. The differential is usually around .11-.15 psi

Not even close. Bogota is 8300', Rio Negro 7200' and many more in South Amercia that are higher. LXV - Leadville is the highest public airport in the US at 9927' and TEX-Telluride 9078' being the highest with commerical service. Aspen @ 7815', Durango 6685', Hayden-Steamboat Springs @6878' and a few more that I cant remember.

Cabin altitude ranges from 4400 feet(27K feet actual A/C altitude) to 8000 feet(41K feet actual A/C altitude). If we should happen to hit 10,000' a horn will sound in the cockpit and if the cabin continues to climb all of the pax O2 mask will fall automatically (we call it the rubber jungle.) Most airliners cruise in the mid 30s.

I'm not sure a GPS-based altimeter would be able to get any sort of reception to work inside a cargo package and inside the hold, but that's what dry runs are for: ship a GPS-based one and have it set to record its maximum altitude reading, then check it when you receive the shipment. You'd then see how well it worked, if it recorded any sort of high reading.

A GPS has an antenna that needs to be able to "see" that satelites. How would it be able to "see" if it is in a shipping box or crate?

Interesting, learn a new thing everyday about airports in the US at least. :) [He did say (with bold added for purposes of demonstration): "The highest commercial service airport that I know of is Denver, which is comfortably below 5,500ft."]

Out of the airports above, I've flown into only three of those and only one of those commercially.

I've landed and taken off from higher airports -- for Asia, in India, China and Tajikistan; for South America, in Argentina, Chile and Peru.

EXCLUSIVE: Homeland Security Secretary Michael Chertoff Offers Chilling Details About 2006 Airplane Plot and Current Terror Threats

Aug. 6, 2007

Terrorists who had planned to detonate gel-based explosives on U.S.-bound flights from London last August would have achieved mass devastation, according to new information from Homeland Security Secretary Michael Chertoff in an exclusive interview with ABC News.

"I think that the plot, in terms of its intent, was looking at devastation on a scale that would have rivaled 9/11," Chertoff told ABC's Pierre Thomas. "If they had succeeded in bringing liquid explosives on seven or eight aircraft, there could have been thousands of lives lost and an enormous economic impact with devastating consequences for international air travel."

They were so close to carrying out this dastardly plot, that 3 of them did not even have passports.

What memory. Do not make it up!!

16 of the 24 questioned have been charged. 2 of these discharged last November and the remaining 14 to go to trial in 2008. On remand and in custody.

Remember police found explosive materials and detonators in their homes.

One of the higher ups was caught in Pakistan and others are still loose

Out of the individuals arrested in the UK at the time for this "plot would have killed thousands", how many have been convicted for the plot itself and/or are still sitting in a jail/prison since the moment they were initially rounded up by the police in the UK last year?

Bangda, Tibet: 14,219'. Highest commercial airport in the world (at least according to Boeing....): http://www.boeing.com/news/releases/...se.950501.html

Who said I was making it up? I was asking. :rolleyes:

Link please to their charges and status of their trials. Show me YOU'RE not making it up.

The same way a GPS antenna can still receive a signal inside a plane, or inside a car, without an externally-mounted antenna. Even my handheld hiking unit with its horizon-only antenna is able to "see" satellites indoors if near a wall or window, though the signal is much weaker than out in the open air.

Commercial units with both horizon and overhead antennas and with better antennas than the tiny one in my handheld unit could potentially receive enough of a signal from in the plane's cargo hold so as to function.

And note that I did specify that a "dry run" through shipping the unit would be necessary to test out whether or not it would work--that's why I said I'm not sure.

Agreed, but likely to equalize once the aircraft climbs out and not sufficient to push the cabin altitude higher - it would push it slightly lower. Given most differentials are in the 7.x-8.x range, a .11-.15 difference is not significant. Law Dawg was asking if the aircraft was fully pressurized for altitude before leaving the ground, which it's not.


Not even close. Bogota is 8300', Rio Negro 7200' and many more in South Amercia that are higher. LXV - Leadville is the highest public airport in the US at 9927' and TEX-Telluride 9078' being the highest with commerical service.

I was referring to major domestic US airports, but you're correct as I totally forgot about ski country. JAC has commercial jet service (in season) and has an elevation of 6451Ft, which is much higher than DEN - but again, it's a regional airport with limited commercial service and unlikely to be a terrorist target.


Cabin altitude ranges from 4400 feet(27K feet actual A/C altitude) to 8000 feet(41K feet actual A/C altitude).

Agreed for most newer aircraft, but some legacy aircraft allowed for higher cabin altitudes of up to 10K. It's unlikely someone can fly one present-day in the US, but some still fly overseas.

Indeed--I suspect most airports from which terrorists would plot to stage a bombing are near sea level, places like JFK, IAD, LAX, etc.

Couldn't one set the barometric altimeter such that when it reached its trigger point of 8,000', that instead of detonating an explosive it could trigger a timer that would start an hour (or whatever time frame) countdown that would then trigger the explosive at cruising altitude? If only all air cargo was screened. :(
