Well yes but they are incredibly expensive to purchase and have a
relatively limited operating range. Jolly nice technology but things
have to move on a long way to get them to be economically rational for
operators.

I saw one on the RV1 this afternoon. I haven't seen one for ages and
thought they'd been withdrawn. Have I just been unloucky/unobservant?
