Not having a go but Why is it taking so long ?
Down to two reasons really, in a case like this. First the Air Accident Investigation Branch is likely to have to give its approval before the aircraft or any debris can be moved/removed - if there is any question of a mechanical failure contributing to the event it is likely that permission will not be granted until someone from there has seen the aircraft
in situ. Second, there may be a need to get special lifting equipment on site to remove the aircraft without causing further damage. Although most airports will have some aircraft recovery equipment, the reality is that it is primarily suited to moving a wrecked aircraft, chopping it up, if necessary. And if the aircraft is recoverable intact, it will usually need the agreement of insurers before anything is done (but I guess this is true for an obvious write-off too, it's just that the insurance company(ies) will want to ensure that a repairable aircraft is removed in a way that satisfies them and their technical experts).
