Flight 77 and The Pentagon

Interesting summary of the issues surrounding the Boeing 757 that was claimed to have hit the Pentagon on 911. I used to work for an airline and spent some time up close to large twin engined planes like the 757 in the hanger and I feel convinced the incredibly large and dense engines and enormous wingspan could not have fitted in the entry hole as shown. Personally I think the building was hit by a cruise missile based on the size of the hole and depth of the penetration of the damage. Also the fact that the plane/missile hit the exact spot in the building  where the missing $2.3 Trillion that Donald Rumsfeld mentioned on September 10, 2001 was being investigated, this is way too much of a coincidence for my liking.
