The pilots of the Institute plame at the airport introduced themselves as Tom Williams, and John Baker. Casual conversation revealed eventually that they used to fly for Oceanic Airlines, before they spotted a UFO and, through a convoluted series of events, wound up working for the Institute.
The plane itself is a heavily modified LearJet 55, covered with an experimental polymer that can render the jet completely invisible to radar when a small electric charge is run through it.
"It's standard on all our planes now. Especially useful for countries where the Institute doesn't having a working relationship with the government," explains Captain Williams.
The flight, even with the advanced Hoffmann Institute engines powering the plane, is long and boring. After many, many hours, you arrive in Greece shortly after noon, local time. For those who have experienced flight before, the landing's fairly rough, due to the rudimentary nature of the airstrip. The current weather conditions are light snowfall. Judging by the maps you've been given, you're about forty miles from the dig site.
Waiting for you at the airstrip is a black Humvee parked by what appears to be a maintenance building. The area seems to be deserted, and the whole thing looks like a temporary affair set up just to get you into the country quickly and without having to bother with customs. The pilots confirm this, and say that they'll be flying back to the US after a few hours of rest. Given that there's no fuel tanks or trucks in sight to refuel the plane, that says a lot about the range of the engines on the plane.
