Pump up the juice!

This is a little different to topping up your car at the servo.

To start with, your car probably doesn't have wings. And it probably doesn't hold 30,000 litres of fuel.

I was intrigued sitting and watching this process of underwing refuelling take place, but was unable to find much information about it.

All I know is that the fuel is pumped in under pressure (up to 50 PSI), and in this application it's being pumped from the reservoir beneath the tarmac. Considering the amount of fuel going in, the process was pretty quick.

If anyone knows how this actually works, or has an animation of it, shoot it my way; I'd love to know! A very cool design - I wonder who came up with it?
