Abstract
The present invention relates to a floatable aircraft such as a parachute balloon. The parachute balloon is comprised an envelope which is able to be collapsed and stored during periods of nonuse. A parachute is attached to the envelope, enabling the parachute balloon to fall safely by the effect of the parachute in various circumstances including the usual descent or an emergency during a fall, such as when out of fuel.

An aircraft comprising:
- an inflatable envelope capable of being collapsed and stored during periods of nonuse;
- a gondola mounted to a lower part of said envelope;
- a parachute which is attached to said envelope;
- and
- a control device for controlling a direction of travel during a descent, said control device permitting selective reduction of upwardly directed air resistance against said parachute by venting of air through said parachute at at least one position therealong.
