Nice! If we get a number of these we could set up a seperate thread. Personal launch videos are always cool.

Thanks for sharing!
From the Mosquito Lagoon, just south of the Haulover Canal, about 12.4 miles from Pad A.
And thanks for the nice words, everyone.

And hopefully someone's recorded it, as I guess I've missed it?

The venting is extremely cool (woo hoo! something I haven't seen before)... Actually looks like the ET is sending out cartoon sound waves (I'm sure there's a better comparison, but I can't think of it.)
And how about that barrel-roll ice debris?

There's one where you want to call NASA TV and say, "Uh.... can we see that again?"

I thought it looked like a comet when it was venting! That was the by far best ET handheld video so far! This flight is just getting better by the minute!

I know this might be Q and A material but why is the venting taking place? Not like the tank needs to be used again and I'm not sure it matters if it still has fuel inside for re-entry...

They don't want the ET to explode due to overpressure. That would create a hazard for the shuttle which is still in the vicinity and may create some orbital debris.

The venting causes the tank to tumble. Makes it break up higher in the atmosphere, I believe

"The liquid oxygen tank contains a separate, pyrotechnically operated, propulsive tumble vent valve at its forward end. At separation, the liquid oxygen tumble vent valve is opened, providing impulse to assist in the separation maneuver and more positive control of the entry aerodynamics of the ET." from
http://science.ksc.nasa.gov/shuttle/technology/sts-newsref/et.htmlI am not sure if my reasoning is also valid.
