Default Aerial photos of launching rocket

At the 12-10-11 FAR Christmas party and launch a helicopter with a Hero video camera attached was hovered above a launching rocket which came within a couple of feet of it. Here is a screen grab of a couple of frames of that video.

This is a 6" x 84" rocket with a 54-1706 Blue Thunder load. It went to 8000 feet. (Corrected in later message)

The 11 second 40.5 megabyte video itself is at:

http://www.v-serv.com/far/new/Helicopter.avi

This video will be the highlight of your year IMHO.

I had the best experience playing it under VLC since it seems to be an avi file in a quicktime container. I set it to loop full screen and it really didn't get old.

That is way cool! Just last night someone was telling me about an R/C plane that was taking video of a launch while in flight - has anyone seen this and/or know where to find it!

Someone posted the video to youtube which makes it more convenient to casual viewers:

http://www.youtube.com/watch?featur...d&v=D8R7mQi9WxA

It came within 2 rotor diameters. Had it hit it, there would not be much copter left and the rocket would be unhurt. That particular copter was used for a guidance system test that makes it a "stable platform", which is the only reason it was not flipped upside down, when the rocket blew by at around 500mph with a pretty good shock wave.

It is a very technically impressive accomplishment of photography.

Jerry,

Very cool video.

A few years ago I was working on a video for an EMRR contest. I used a Booster Vision mini-cam to try to photgraph an Estes Snitch from a lot of different angles. Eldred P. and I laughed ourselves nearly to incontinence trying to hit the mini-cam held over the launch pad with a 10 foot pole. We must have done 15 flights with a slow-moving Snitch, at only 10 feet, and we never came anywhere near as close as they did in your video.

Again, thanks for posting it.
