As regards the first group, the overall conclusion is that the approach of the aircraft and its being damaged cannot have taken place in the the manner put forward in the Report. This conclusion is supported by the following observations:
the aircraft's reported 42� approach angle is not possible for a B-757; >>
the aircraft's right wing's hitting a generator cannot account for the narrowness and discontinuity of the damage to the facade as proposed by the Report; >>
the intact cable spools in the trajectory of the aircaft are incompatible with the information on the impact contained in the Report; >> and,
there is no evidence to support the claim of the left engine having hit a vent structure; such a hit would also not explain the narrowness of the damage to the facade. >>
For the second group, the overall conclusion is that the Report"
