Actually PDR, I think you're confusing the 1/3 from the North Pole to the South Pole and 1/3 around the circle.

send two in one direction
and the third in the exact opposite
half way to the south pole transfer the remaining fuel on one aircraft
with a full tank this plane can finish the 1/4 to 3/4 legs of the journey
meeting with the third aircraft and refueling with the remainder
our plane can now finish the circumventing of this planet

It sounds a bit messy, and I assume things happen instantly, but it works, doesn't it??



This, to me, is the ONLY good solution where AT LEAST ONE airplane litterally goes AROUND THE GLOBE as the puzzle demanded.
And if even Rookie agrees...

Rookie's own solution is quicker, and less messy, but it just flies back and forth across one side of the planet.

My own brain staggered on this one, I must admit. This isn't the kind of puzzle I'm 'designed' for

Really great thinking.

...but gravity is stronger at the poles, thus using more fuel.

Couldn't you just fill the tank of the airplane full then put another tank of gass on the plane so that when the airplane's tank starts to run low, you could just refill it?

You guys are missing the simplest solution. 2 planes start to the south, at 1/2 way the #2 plane transfers the remaining 1/2 tank of fuel to plane #1, which continues on. Plane 2 ditches in the ocean. Plane #3 takes off in the opposite direction of #1 and at the 1/2 way point transfers 1/2 tank fuel (then also ditches) to #3 which continues on to return at airport. The only proviso is that 1 craft returns to airport, thus the other 2 are expendable. It is all in the timing. Mike

Thank you Mike! Everybody is giving these complicated answers, none of which involve ditching planes, and the most obvious/simple one was not mentioned until you posted. The problem stipulates nothing about the ditching of planes being frowned upon, although I do give props to those who worked around the destruction of aircraft.

Actually, the riddle does stipulate that all planes must return to the airport... My question is, how can there only be one airport? Usually with air travel there is an origin and a destination. If there are no other airports, where do the planes fly to? And why would they build at the north pole where jet fuel and other critical fluids would constantly be at risk of freezing? Not to mention the exhorborent costs involved in keeping the planes de-iced... This sounds more like an illogic puzzle to me...
