Most of the Post Office supervisors seem to think that distribution by air will continue and that the railways will suffer the most.. .. .Apparently there was to be review of the air operation during 2003/2004 but this has been bought forward to this year and the general opinion is of larger aircraft being required.. .. .Ten years ago, it was mainly Bandits (1500kg), now it is Sheds (3000kg) and F27/748's (6000kg). Wouldn't be surprised if the next change will be to containerised 146's (9000kg) and/or ATP's (8000kg).
