They don't operate a training school at the moment (but check as it's been a while since I worked there), but were looking at it. They are avalible for all types of charter work, but EMS is their core bussiness.
I'm sure they could arrange a flight with one of their C&T guy's (most management and pilots all have good English) The 427 is a really nice helicopter to fly.
Talk to the OPS Manager, Martin Skvrne in Brno.
A direct flight from London to Brno will have you at the head office location.
Great bunch of people and very professional organization.
