As far as I can see, this thread is simply Distant Voice using the anniversary of the accident to bang his drum yet again. The facts of this tragic accident seem to have been all too clear at the time, and it is in my view wholly inappropriate for DV to assert that the takeoff was in violation of a curfew which did not exist and that an incidence of birdstrike must mean that the airfield search was inadequate simply to promote his argument.
In so far as he has a point, it has already and repeatedly been made elsewhere.
