Perhaps one of the best feelings you can get from a roller coaster, besides the speed is what is called airtime. Airtime is the sensation you get from when your rear leaves the seat when the coaster goes over a hill. 

There are two types of airtime: floater and ejector

What's the difference? Well, it all has to do with 3 conditions:

• The length of the hill
• The shape of the hill
• The speed of the coaster

Floater airtime is mainly found on the older style wooden coasters like Shivering Timbers at Michigan's Adventure and B&M hyper coasters. Floater airtime is characterized by a slower upward feeling when cresting a hill. It's rather gentle. 

On the other hand, ejector airtime is found on coasters with tight layouts and hills that have a more pointed shape and coasters that traverse these hills faster. GCI woodies like Thunderhead at Dollywood have ejector airtime. 

Me? I like both. Sometimes, rides have a combination of both floater and ejector airtime moments. What's more, coasters can have a full combination of both in one hill. We enthusiasts call this "floajector" airtime. 

So what about you?
