>What plane can approach at that speed based on the runway provided?
It is impossible for a commercial airplane to hit the Pentagon from that angle because they would first have to survive the wings being clipped by utility and telephone poles; it was a missile. And by logic alone, how can the same type of plane take down a steel sky scraper hundreds of times bigger yet was only able to knock down a few bricks off the front door of the Pentagon? It was an inside job with missile.
