guys, i just read this: Flightcraft brought out a new freeware AI Vulcan K.2 to be used in air to air refuelings! At this point, it won't be possible to actually transfer fuel (like it was in the payware Lago Tornado Pakcage), but that will be fixed in a further release.

here's the link to the download: http://www.flightcraft-simulations.co.uk/tanker.html

have fun guys!
