A story comes from Dr. Eli Raz, ILPHO. They have built a huge hot-air balloon for something [TODO add picture]. It was unconnected for a while and then accidentally risen and flew away. Eli went after it fast with a car to ramot itshak.
When he came, someone was nearly finished packing it into his SUV. Eli: "I am sorry, this is my balloon". The guy - "No, it's mine. I found it first!"
The balloon was successfully returned to owners.
