Professor Fukano succeeded in the challenge

She gives him 45 kiloliters of her remaining 90,leaving them with 45 each.But that's just half of what they need to make it to the airport.Fortunately, this is exactly when Fugōri,having refueled, takes off.45 minutes later, just as the other two planes are about to run empty,he meets them at the 315 degree point and transfers 45 kiloliters of fuel to each, leaving 45 for himself.All three planes land at the airport just as their fuel gauges reach zero.As the reporters and photographers cheer,the professor promises his planes will soon be available for commercial flights,just as soon as they figure out how to keep their inflight meals from spilling everywhere.
