3 fully identical planes (P1, P2 and P3) take off at the same time.
P2 and P3 are used as support planes: they can instantly refuel P1 and each other.
P2 and P3 must both return safely to the starting point: meaning they can't run out of fuel.
Using 1 mile per gallon and 300 gallon tanks, by how many miles can P1's range be increased?

Try having P3 refill P1 and P2 (back to 300 gallons) at same time, then returning to start point...

Bit of an improvement:
All three fly 75 miles, leaving them with 225 gals. P3 gives 75 gals each to P1 and P2, leaving them with 300 galls and himself 75. He heads home.
P1 and P2 fly a further 75 miles, leaving them with 225 gals and 150 miles from home. P2 transfers 75 galls to P1 leaving P1 full-up and himdelf just enough to get back for breakfast.
P1 can now fly a further 300 miles, making 450 in total.
To waste one second of one's life is a betrayal of one's self. I wonder what's on television...?
