Dear me, this is ancient history, isnt it!
Yellow and white A109s have been regular visitors all over UK since 86 or so. They tend to attract attention on their visits to Battersea on account of their lack of any form of registration or markings despite being in a very similar livery to a well known local charter operator.
They are as far as I know 109A s and therefore severely payload/performance/range limited and would be regarded by civil operators as a waste of space.
I hope Im wrong on the last para but I fear not.
