- At 1/8 circumference, each plane has used 1/4 of its fuel. R1 tops off both S and R2 then returns home empty.
- At 1/4 circumference, S and R2 each have used 1/4 of their fuel again. R2 refuels S and then returns home empty.
- S continues around until 3/4 circumference (now on fumes) where it is immediately met by R1 who, upon returning home, refueled and headed the other direction to meet S. R1 used 1/2 of its fuel getting there, so it gives S 1/4 of its fuel and both planes fly on together.
- At 7/8 circumference, S and R1 (now both on fumes) are met by R2, who also refueled upon returning and headed the other direction. R2 has used 1/4 of it?s fuel to get to this point, so it gives S and R1 each 1/4 tank and they all make it home together with just enough fuel to land.

So, 3 planes total.
