Budge,

Can you jpg the graphic labelled "Crossing California"?

Let's see if we can predict the location of the object that separated from the orbiter and observed by the astronomers in Owens Valley.

Let's do an elementary physics problem. An object has a particular height and velocity. Calculate the distance that the object travels prior to impact.

Y = height
v = velocity

On the slide labelled "Crossing California" a blue dot over Yosemite National Park is labelled with the following data:
13:54:20 GMT +/- 60 sec (34)
(13:53:20/55:20)
Start of slow aileron trim change. GMT is approximate
Let us assume that the vehicle had increased drag just prior to this point due to a component that is creating drag.

Let is attempt to estimate the point at which the object creating the drag separated from the vehicle by comparing the astronomical observations with the inflight data acquired by Mission Control and then released by NASA.

The prior data point which NASA labelled is at:
13:54:10 GMT (33)
38.4162, -120.1739
LMG Brake Line Temp B - Start of Off-Nominal Trend - Temp Increase. H = 228460 ft. Mach 22.64
I will define this data point as CA-1

A second datapoint is labelled at:
13:54:24 GMT (35.5)
38.27043, -119.0681
Sys 3 LMG strut Actuator Temp - start of off-nominal trend - unusual temp rise
H=227437 ft
V=Mach 22.51

Using the two datapoints, I have created a line on my Microsoft MapPoint program (which appears to be the same program NASA is using).

I'm going to attempt to find the discussion written by the Cal Tech astronomers.

Interesting idea, estimating the location.

At this point, I would estimate that the molecules are floating somewhere over the mid-atlantic.

I don't think any of the western 'flares' reached the ground. However, I may be wrong. That big one may be out there somewhere, but it seems to me that the flares over Owens Valley were only small ones.

This is the time line of the shuttle coming out of the southwest corner of Utah and into the northwest corner of Arizona. The kids filming at Waputki National Monument, northeast of Flagstaff will be picking the shuttle up at any moment on film, if they haven't already.

The shuttle is crossing northern Arizona according to this time line and is under observation by the kids filming at Waputki NationalMonument.

Below are the two final sensor readings from NASA, as the shuttle crosses northern Arizona and into New Mexico air space.

south of Shonto, Arizona
13:56:24 GMT
Left Upper Wing Skin Temp- Start of Off- Nominal Trend Temp Reading Trending Down potential sensor/wire damage
H 220,235
mach 21.17

southeast of Shonto, Arizona
13:56:30
1st Roll Reversal Initiation
H 219,820
mach 21.13

The shuttle passes out of range of the kids video camera and crosses into New Mexico. 23 seconds elapse before the next sensor reading provides NASA any kind of useful data.

east of Tohatchi, New Mexico
13:56:53 GMT
SYS 3 Left Main Gear Strut Actuator Temp Temp Rise rate Change from 1.7 F/min to 12.9 F/min (not increasing) to LOS
H 218,839
mach 20.80

The shuttle took 1:04 to cross out of Utah, across Arizona, and into New Mexico.

At approx. 13:56:02 GMT the shuttle sent data out, as it entered Arizona airspace. The last bit of data sent from the shuttle while in Arizona came at 13:56:30. That's 28 seconds of data that can be married up (sync.) to the kid's film that was taken from Waputki National Monument.

Sure.
