Does it look like an airplane? No, it looks like a brick with wings. (NASA humor... that's what the astronauts call it.) It is technically just a glider during re-entry and landing - it is "flying" solely on gravity only and cannot propel itself. It is smaller than a commercial airliner and moving pretty fast until just before landing. It will "glide" faster than the speed of sound - hence the sonic booms - until just before landing when it hits the air brakes pretty hard on its final descent.
So the chances of you seeing anything are extremely small. You have to know where to look and at what time. In fact, the only place you have a "good" chance of seeing it land will be if you are very nearby to the landing site. Any further away and you probably will miss it due to its speed and will only know you missed it when you hear the sonic boom. But if you know it is coming and are certain of where it is coming from, you can see it if you watch closely enough.
