12. Ricky Brookes, of Liverpool, asks the question:

ANSWER
13. Michael Domingo, of Dallas, Texas, asks the question:
I live in the Dallas, Texas, area. One night back in 1999 (STS-96?), we got to see a shuttle as it re-entered the Earth's atmosphere on its way to landing at KSC. It looked like an airplane-shaped fireball and trailed beautiful white smoke across the horizon. Will we be able to see this again someday? What circumstances have to come together to make this happen?

17. Carsten Feilberg, of Copenhagen, Denmark , asks the question:

ANSWER
18. Jeff Kupke, of Dover, N.J., asks the question:
I have noticed that on the screen which shows the shuttle's (or station's) current orientation and attitude, you can see the Tracking and Data Relay Satellites, and that you can see each satellite's approximate coverage area. My question is, why does each one have a small chunk missing from it's coverage area, rather than a perfect circle? Is it due to antenna orientation on the satellite?
