Do jetpacks exist?

There are multiple examples of functional jetpack technology, though not all of these machines make use of jet propulsion technology, and very few of them approach the functionality of those jet packs seen in science fiction or cartoons. Some real-life jet packs only make very limited flights, while others are more like machine-powered parachutes that don't have the ability to lift off from the ground independently.

Additionally, the price tag for these jet packs tend to be astronomical, with some costing upwards of $50,000 each, making them more expensive than an economy car and meaning that the average person probably won't be zipping about on a jetpack anytime soon, as of 2015.
