ANS remains an unknown entity to most and is building a poor reputation - last week's EFPS failure, one example.
Their ATCO training scheme and its success is unknown. Job security, unknown. ANS do approach radar at Edinburgh only, potential for dual ratings.

Worth noting, since some initial 'success' in securing the ATC Tower contracts at Gatwick & Edinburgh (co-incidentally owned/operated by the same company at the time), ANS have failed to gain any further major business in the UK...
