Private plane has a small propeller-type engine and is used by indi- viduals to transport themselves or their friends on small trips for business or pleasure.

Helicopter has a horizontally rotating pro- peller (rotors) that lifts the craft upward and forward. This type of craft is used for trans- porting just a few individuals over short dis-
