Question: is a hot air balloon considered an aircraft

title: Hot air balloon
text: A hot air balloon is a lighter - than - air aircraft consisting of a bag , called an envelope , which contains heated air . Suspended beneath is a gondola or wicker basket ( in some long - distance or high - altitude balloons , a capsule ) , which carries passengers and ( usually ) a source of heat , in most cases an open flame . The heated air inside the envelope makes it buoyant since it has a lower density than the colder air outside the envelope . As with all aircraft , hot air balloons can not fly beyond the atmosphere . Unlike gas balloons , the envelope does not have to be sealed at the bottom , since the air near the bottom of the envelope is at the same pressure as the surrounding air . In modern sport balloons the envelope is generally made from nylon fabric and the inlet of the balloon ( closest to the burner flame ) is made from a fire resistant material such as Nomex . Modern balloons have been made in all kinds of shapes , such as rocket ships and the shapes of various commercial products , though the traditional shape is used for most non-commercial , and many commercial , applications . 

Answer: answer: Yes. A hot air balloon is a lighter - than - air aircraft. It consists of a bag, called an envelope , which contains heated air and as with all aircraft, hot air balloons can not fly beyond the atmosphere
answer: Yes. A hot air balloon is a lighter-than-air aircraft. It consists of a bag called an envelope, which contains heated air, and as with all aircraft, hot air balloons can not fly beyond the atmosphere.
