A final word on the subject of the safety of air travel compared to motor vehicle travel:

Here are some statistics and basis math. Again, this is no complicated. You don't need a master's in mathematics. No calculus is required. If you graduated from elementary school and have even a passing familiarity with simple logic, you should be able to comprehend this.

From the decade between 1999 and 2008, the fatality rate per 100,000,000 passenger miles* is as follows:
Cars: 0.72
Vans, SUVs, pick-up trucks: 0.73
Airlines: 0.01
http://static.mgnetwork.com/rtd/pdfs...athrates11.pdf

* - Understand what passenger miles means - it means that a 500-mile flight with 100 people accounts for 50x as many passenger miles as a 500-mile road-trip with 2 people, so don't get all hung up on the disparate capacities of airliners and cars, as this methodology accounts for that.

So, if you drive 20 miles to the airport and then fly 1000 miles, you're more likely to die driving to the airport.

This is not a matter of subjective opinion. It's math. It's hard facts.

Again, people have a fear of flying. You can give all the stats you want, it won't change things. End of story.

It's pure speculation at this point, but it wouldn't surprise me if it turns out that there was some minor distraction occurring in the cockpit, and no one was actually paying attention to flying the airplane. Wouldn't be the first time it's happened. What makes me think that is the fact that there was no distress call. If & when it's recovered, the Cockpit Voice Recorder should tell the story.

So I just heard a pundit on the radio mention that the plane descended approximately 80 feet per second for approximately 8 minutes. I haven't had a chance to see or hear most of the details that are out there; but, assuming that's correct - even at a diagonal descent - is that fast enough to feel it? I mean, I can "feel" when I'm on a plane that begins it's descent on approach to land; but I have no idea how fast/how far we are dropping. Just wondering if that rate of descent would have had a discernable feel to it?

(Sorry - had to edit that to what I actually heard - 80 ft per second.). And a post on another thread says over 14000 ft in 36 seconds which would be what, about 400 ft per second? Obviously I need to get my hearing checked...or go back to believing 0.00001% of what I hear.

Just reported: One of the pilots was locked out of the cockpit before the plane crashed.

Not true. Once again, not everyone flys while most drive or ride in a car. Then, death rates for car accidents are greatly affected by where those accidents happen and the conditions under which they happen. Compare the death rates for people driving a car and hitting the ground or side of a hill to those flying where the plane hits the ground or side of a hill and then you might have a valid comparison, otherwise it is selective statistics and means diddly squat.

Also, the memory card was not in the FDR when the FDR was recovered. Weird.

Highly unlikely, more likely, you just made it up. The data and flight recorder contents haven't been revealed.
