What is a hot air balloon?

1 Answer

Answer :

At the end of a hot air balloon flight the heated air inside isallowed to escape through a panel that is opened either in the topor side of the balloon envelope. The crew then squeezes theremaining air our of the envelope and then packs it away in a largebag ready for the next flight. This process is called deflating theballoon

Description : One sunny afternoon, three men go for a ride on a hot air balloon over the Sahara desert. An hour into the trip, the balloon begins to lose altitude. A month later, someone found one of the ballooners laying on the desert sand dead, naked, and holding half a toothpick. What happened to him? -Riddles

Last Answer : As the balloon lost altitude, the men took of their clothes and threw them overboard to decrease the weight of the balloon. The balloon continued to drop so the men drew straws to see who would be forced to jump. The dead man in the desert drew the shortest one (the half toothpick).
