According to the NIST report, the south face of WTC 7 had damage between two exterior columns - roof level down 5 to 10 floors, extent not known. The picture below was taken while WTC 1 was still collapsing. The photographer was on the Brooklyn Bridge and captured a clear shot of the upper floors of WTC 7 from the south and east, before the building was obscured by smoke after the collapse
The south side of the top of WTC 7 is very clear in this image. It is also clear that there is no gash. The debris coming down did not reach the top floors of WTC 7.
