Let's not exaggerate the situation here "missed the Rock in GIB by 200 feet" is highly misleading, as the report states:
"The lowest altitude of the aircraft when over the land was 2,100 ft. The hghest point on the land, just south of the airfield, is 1,420 ft."
Just because the highest point on the land is 1,420ft, does not mean the aircraft was flying over that point at the time. Indeed if you look at the report (Figure 1), it was not.
