Imaginary Expressive Object - Personal Jetpack

When I was asked to think up an imaginary object, the one object that immediately popped into my head was for people to have their own personal jetpack. The jetpack would operate by taking two small jet-powered engines and strapping them to a heavy duty backpack filled with fuel. The jetpack could even use high powered fans and a battery to function. To operate it, there would be two hand controls on each side. On one side, a user would have the thrust for desired height and the other side would be forward/backward and side to side movement. Though the jetpack does exist, it is rarely seen and is not used by the majority of the population today. The jetpack is both necessary and fun. It is necessary because if the engines are made efficiently, it would cut the cost of fuel when compared to modern day cars. It would also be fun to just fly around everywhere you go. However, there are some downfalls to the jetpack. On one hand, you could be 2000 feet in the air and run out of fuel. Another case would be if one or both of the engines malfunctioned. These problems could be fixed by mounting a parachute mechanism somehow inside the backpack section of it
