After the tragic East Midlands accident in the mid nineties, when a Police AS355 crashed just after taking off from a remote site, and no one knew that the A/C had gone down. The CAA made pre and post take off and landing calls to the operational Control room mandatory.
Very little seems to have been released by the police as to what contact they had with that aircraft (a) during the mission as a whole and (b) round about the time of the accident. One thing is clear and that is that had the accident not happened, then that aircraft would have been landing very soon after. Therefore, I would have expected such preliminary contact to have already taken place. This has not been subject to any comment as far as I can see.
