Two men from Oregon tried to fly to Montana with their lawn chairs tied to ballons.
About seven hours into their trip, they had to land because of a storm.
The men were hit by hail and snow. They did make it to the ground safely.
Their aircraft ,however, was lifted back into the sky.
The men said they don't know if they will be able to find their lawn chairs.
They also said they were not sure if they would try the stunt again.
