Value
The helicopter the leader is in has the most value! He would only choose to fly the very best one, after all. That's why it's worth way more than the others. Actually, any helicopter he flies goes up in value. That's the amazing effect of a good leader.

To further increase the helicopter's value, the leader bought himself a car (か) and then tied them together. Now it has the value of a helicopter AND a car! Wow!
