I have not any experience of the trip.I have watch balloon match on TV.There are many kinds of balloon.As i know that,balloons have been used for exploration of the upper atmosphere and stratosphere.Such observations help the forecasters predict the weather in the future.

Yes,balloon use for air research.I am intersting in the trip of balloon in the air. Althought it are not easy to steer,and can only travel as fast as they are pushed by the wind,they have served an important function by introducing people to pleasures and problems of flight.Through the use of balloons it bacame evident that it was indeed possible for people to trave in the air.
