Challenger Disaster website update 12/2/2003

I have updated my website with a new video.

http://www.challengerdisaster.info

TV-3 was the closest broadcast TV tracking camera at the time of the STS
51-L launch. Located southeast of launch pad 39B, Universal Camera Site 12
is a stone's throw from the Atlantic ocean. The proximity of this camera to
the launch pad provides a view that dramatically captures the roll maneuver
as the Shuttle turns to its launch azimuth. You can clearly observe the
erratic paths of the SRBs as they speed downrange. You may recognize this
angle as belonging to Engineering camera E-217 if you are familiar with the
Roger's report. Also of note is the significantly higher sound level during
the launch. If you compare the TV-3 audio (one mile from pad) to TV-4 which
is about 3 miles from the pad, you will note that you can hear the SRBs in
about five seconds after T=0 and fifteen seconds respectively. Finally, I
have added time tagging and a few frame descriptors to this particular angle
to aid in discussion for this particular angle because there are some
interesting visible phenomena at various times in the flight.

Nicely done Daniel. You must be paying for some serious bandwidth.

Define serious;-)

The site is now back online. Much quicker than I thought too.

TV-1 was a great deal closer (reference Figure 46, The Betrayal
of Mission 51-L). NASA Select switched to TV-1 for the RSD of
the 51-L SRBs (reference Figure 22, The Betrayal of Mission 51-L;
Figure 22 is online at www.mission51l.com/chapter1.htm, page 6).

Also of note is the significantly higher sound level during
the launch.

The TV-1 soundtrack is much noisier (reference the video tape
which I mailed you from Cocoa in the summer of 1986, a collection
obtained via the FOIA by some McDonnell-Douglas employees).
