[Cold Heat]

I have discovered a few interesting things about Columbia.

It was the oldest f course but was also the most problem ridden. The left wing heating and left side heating problems are mentioned early in the program. Special equipment and cameras were once installed to observe and correct it.

Also, the tile arrangement was different on the trailing edges of the wings.

There was a still photo broadcast yesterday that showed damage on a previous flight, where it had lost a number of tiles. Burned about an 8-12 inch hole into the infrastructure. Don't know if it was Columbia or not.
