It is not set on fire. As the space shuttle enters the atmosphere it is moving extremely fast, more than 17,000 miles per hour. In incredible speed causes the air around it to heat up to the point that it glows.
Space Shuttle Columbia
Columbia heated up and broke apart while entering the atmosphere.
The Space Shuttle Columbia disintegrated while re-entering the atmosphere; it did not explode.
Although it reaches incredible speeds, a Space Shuttle is not going fast when it enters the atmosphere. The gravitational pull of Earth, or just gravity, are pulling down on the space shuttle with immense force.
It was the Columbia, the first space shuttle to be flown into space more than twenty years earlier.

The space shuttle heats up when it enters the atmosphere because it encounters friction from the atmosphere. This is why the space shuttle is covered with special tiles that dissipates heat very quickly. You can hold a red hot one with the tips of your fingers. At the time of the deorbit burn the space shuttle is going 14,500 miles an hour. The atmosphere friction slows it down slow enough it open it's parachutes.
If the space shuttle is exiting the atmosphere, that means you are going into space then no the windows will not turn red. However if you are entering the atmosphere the friction caused by air molecules hitting the orbiter will create plasma around the shuttle. You will see a reddish orange glow out the windows but the windows themselves will not turn red.
the space shuttle travel in the trophosphere.
Second space shuttle in space was Challenger, but second space shuttle ever was Enterprise, what was made for testing in atmosphere.
A space shuttle still has to leave the atmosphere, we aren't building them in space. While leaving the atmosphere a space shuttle causes a lot of friction as it rubs against the air on the way up.
== == The space shuttle Columbia broke apart and partially burned up while re-entering earth's atmosphere over Texas on February 1, 2003. The entire seven member crew were killed.
