Three soldiers are in a hot air balloon

Three soldiers are in a hot air balloon, riding over a town with a mountain in the distance. As the mountain approaches, the sudden realization hits that they will not clear mountain.

In a last-ditch effort, they try to throw out everything they can. The first soldier throws out their weapons, swords and such. Seeing as that wasn't enough, the second soldier throws out their boxes of food rations. Still not enough, the last soldier throws out a bomb, which was critical for their mission, but as they were not going to complete the mission regardless, it was better than dying.

With the dropping of the bomb, they end up in the clear. They land, but as they had no bomb, they aborted the mission and went back to town to call it into HQ.

On their way back, they see a crowd gathered. Upon further inspection, the soldiers see that some were cheering, some were crying and looked sad, and one person looking extremely confused and embarassed. The soldiers asked, "what happened?"

The crying: "Swords fell out of the sky and killed our brothers and sisters!"

The cheering: "But now we have weapons to fight against the bandits! "

The crying: "And then a heavy box fell on top of one of our elders and killed him!"

The cheering: "But it was filled with food to last us weeks!"

The soldiers, understanding that this was their doing, sympathized and asked, "and what happened to him?" while pointing to the man that looked confused.

He replied, "I farted and my house blew up!"
