This is a good reminder for everyone to put attention to the safety video and/or demonstration flight attendants show/do prior to departing. I know that for many people, frequent travelers in particular, its easy to dismiss such safety protocol thinking that it might not happen or that you already "know" what to do.
While most of us will not be in an airplane accident, most doesn't mean all.

Not at all. When a plane loses thrust, the other three physical forces are still active: lift, drag and gravity, lift being the most important of those for it to glide.What is really amazing is that the pilot was able to land the plane solely by gliding, ie w/o any power from the engines. From what I understand this is most difficult if not nearly impossible to do.

A plane becomes a glider when it loses power. My 182 had a 10:1 glide ratio. I speculate a big plane has a 3:1 or something, maybe less, depending on the speed, and speed-reducing drag. But it'll glide. Not pretty but prolly enough to be controllable...as long as there is some speed (air flow over the airfoils, wing, elevator and rudder).
Here is a prime example:
Gimli Glider - Wikipedia, the free encyclopedia
I suspect since he was climbing and didn't have a lot of altitude, he wasn't able to get into Max Glide Configuration...prolly was at less that 16:1.CB
The only "similar" craft I can compare would be the C 9 and that is about 16:1,(these are figures for optimum altitude, speed and clean congiguration) given the high wing loading of the C 9 I would think the AB 320 would have an even higher glide ratio
He should have been in area of altitude loss of 1000' per mile
From pictures I have seen post 'crash" ,either the engines were windmilling sufficiently to power hydraulics or the RAT dropped as slats were deployed and flaps at 15o or so
From the graphics on TV today, it look sas though he had a normal departure, bird strike on left turnout, thought about straight ahead for Tetebor, realized too far and did a downwind landing in the water
Poor guy never left the pattern!

Big difference here is the pilots had over 28,000 feet of energy, an old Canadian AF base and actually had too much energy gong inot that approach as they had to side slip the aircraft to lose altitude
Not saying the Canadian Pilots did not do a great job, just that the USAIR pilots had only seconds to make critical decisions
Hope Air Canada checks the tires and gas gauge next time
