They made it first.. I've been a fan for a long time. Seems like the trick is specialty motors efficient at low power and some monster propellers. Of course it's all about weight, too. Also Li-ion batteries have better energy to weight ratio than Li-Po batteries so you can easily double your flight time just by converting to Li-ion.

Sky-sailor was first but the Solar Impule team is the first with a person onboard. Cheers!
