He quite clearly DID hear the plane. The people next to him saw the plane. Of course, looking up, the plane would have only been visible for a fraction of a second before entering the building. Now, seeing as how he was taking a picture at the time, and being a semi-professional photographer myself, I happen to know that when you're looking through the viewfinder and take a picture, the mirror opens up effectively blocking your view, the shutters open, the picture is taken, the shutters close, and the mirror comes down. Total time on a professional camera is anywhere from a tenth of a second to a twentieth of a second in bright sunlight. David couldn't have seen the plane because he was already taking the picture as one can clearly see from his photograph. There is no way he could have swung the camera up, got the picture in focus, and taken the picture fast enough to get the very first moments of the explosion. Funny enough is that David Handschuh believes the plane hit the building. He understands a simple fact that some truthers here just can't wrap their tiny minds around; you don't have to see something for it to have happened. Yes, the plane came in fast and he didn't actually see the plane. Does this mean the plane didn't hit? No. Yet some will ignorantly pretend that he REALLY means there was no plane. Truther games are very predictable.
