Several jeeps are poised at base camp on the edge of a desert aiming to escort one of them as far as possible into the desert, while the others return to camp. They all have full tanks of gas and share their fuel to maximize penetration. In a friendly desert it is best to leave caches of fuel along the way to help returning jeeps. We solve the problem in a hostile desert where it is not prudent to leave unattended fuel deposits. A surprising result is that deeper penetration can be achieved if the jeeps stagger their departure times rather than all leaving camp together.
