Here's how it works .. you register (for free), download the small unobtrusive program (for free) then goto the site, pick an assignment and an aircraft, fly it, get paid and then do it all over again. Simple (and free).
If you love bush flying, then this will give you reason to fly (i've been trying for the last few days to make enough cash to buy my first plane). The largest aircraft it supports is the DC 3 or beach1900 so there's no jets and no really long haul stuff here. all i can say is head to the site, have a look and let me know what you think.
