Okay, so they were going to be transported in a helicopter, then a jet, and now it is a big enough airplane to hold an ambulance. It will fly into a city 20 minutes from where they are. The ambulance will then drive off and pick them up and then drive back to the airport and fly them all to Vienna. The airplane is coming from a NATO airbase, not sure on the exact location. The airport doesn't open until 2:30am Tuesday morning so they should be picked up around 3am.
I'll keep you posted.
