Subortal space flight

It has been very common in the last few years. A suborbital space craft fly's a lot higher than a normal aircraft. They can go up to 100 km high, it means they aren't totally in outer space but is high enough people on board wouldn't feel gravity. However the plane will not go high enough to orbit around earth. It is mainly for tourism so people can go into space. The tickets are cheaper than a rocket but still a lot. Sometimes the planes carry things to launch into space if they think its important enought to use space on the aircraft
