To support plane AAA
First 3 planes (A,B,C):
A give B it's 1/3 gas at degree 60
thus B can fly to degree 90 and give AAA 1/3 gas
C can give AAA 1/6 gas at degree 75.
Therefore, AAA can have full gas at degree 90
and AAA can fly to degree 270.

And the same procedure for the other direction.

AAA can't have full tank of fuel at degree 90 - 匆匆过客 (41 bytes) 2006-09-29, 14:57:31 (105145)
- AAA got 1/3 at 60 from B and 1/6 from C at 75 - 4U4luC2 (71 bytes) 2006-09-29, 15:02:01 (105149)
- no, last fueling at 90 degree by plane B. - wavelet (34 bytes) 2006-09-29, 14:58:50 (105147)
  - right. i missed the refueling from plane b since it's so up there (无内容) - 匆匆过客 (0 bytes) 2006-09-29, 15:05:23 (105150)
