Amazing raw video from various surveillance cameras of the US Airways Flight 1549 crash landing into the Hudson Riveron January 15, 2009. All 155 passengers aboard the plane survived in what is being called "Miracle on the Hudson."

Wow — just wow.

This is the first I’ve seen the actual touchdown, which the Coast Guard video didn’t catch. Assuming that it plays in real time, I measured 0.36 seconds for it to travel its length of 123 feet. This gives a touchdown speed of 123/0.36 * (60/88) ~= 230 mph.
Did you see the other plane on display in the 2nd video near the end of the video ? is that the Concord ?
Yes... been there a while....

Headline?
Obama gets word of pending tragedy, acts quickly; not like Bush's Katrina
Network Movie To Air Next Week, "Miracle on the Hudson."
President-elect Obama positioned rescue boats at site, assured pilot and passengers.
Some college kids at Parks College did a simulation in a trainer and set touchdown for 125 mph, then raised the speed to 140 mph, so as to avoid a stall. The book states landing speed is 200 kph, which is 124 mph. Take off is 250 kph, which is 155 mph. Variables would alter the speeds somewhat. I believe that the black box will reveal this detail.
Not trying to be a party pooper. ;o)
Color me skeptical. Why does the camera move in some of the videos if it’s a “surveliance” camera?
Well, my 0.36 second timing is highly suspect. I tried timing a longer interval, and measuring the length of the plane on the screen for comparison. This time I got 2.28 seconds to go 10.5 cm on the screen, where the plane measures 3.0 cm. This gives 0.65 seconds, and revises the speed to 230*0.36/0.65 = 127 mph.
If done properly, this sort of video analysis can can yield pretty good results.
My guess is that someone monitors the surveillance cameras and can manually operate them if he sees anything unusual.
At this link on FOX, it shows the camera doing close ups, then a real quick pan of the surrounding area as if someone is looking to make sure everything else is quiet, then back to the scene.

127mph... that’s a good number I think. Just watching the landing, ‘looks’ slow, as far as airliner landings go.
I’ve used a household yardstick on a few occassions to measure something on my monitor for close (like a hand grenade close) estimations.
