You need to know the map of the area. This guy has the world's most incredible vision, obviously.
First, he's describing 20 metre streams of molten metal from WTC 1. Yeah? He was on the corner of Fulton and Broadway (I know exactly where he got off the Lexington Ave train from his narrative.
That was 3 full blocks, laterally, from WTC 1, and 900 to 1000 feet up. And he could make out that it was molten metal???? From his vast experience in the foundry at Merrill Lynch? Obvious BS. (He was probably looking at burning jet fuel - he's talking about the period within minutes of the first strike.)
Secondly, you have to get about 25 minutes in to hear his BS on WTC 7. He refers to the first collapse and he's already walked past City Hall up to the lower edge of Chinatown???!!!! Where's a damned tour guide when you need one?

In short, he was about a 3/4 of a mile to a mile away and he smugly tells the camera that he didn't see anything hit WTC 7, "from where I was". Well, no, idiot. You couldn't have seen Vesey Street from Chinatown! And besides, you flipping idiot, WTC 2 (not 1) was the first to fall and it didn't do the damage to WTC7. But his whole demeanour is that this is some sort of proof - the irrefutable WTC 7 evidence that he didn't see from street level in Chinatown.
Thirdly, he admits that the plane approaching WTC 2 might've been blocked from his vision. No "might"! He was on Broadway. The plane approached from roughly the West-Southwest and would've been behind the tower so he wouldn't have seen it.
Fourthly, I also believe he's flat out lying when he asserts that the cleanup trucks arriving the same day and hauling away debris. Literally the first day. He wasn't there - he'd already run away up to Chinatown and headed out of the area. So he's reciting crap from some troofer site (this nonsense starts at roughly the 30 minute mark when the interviewer starts throwing him softball questions).
The feed is horrible, getting slower and slower and finally stops altogether when he's talking about his horrible memories and getting over the trauma. I don't know where he's going with this part because I can't get the last ten minutes or so to play. Sounds like the same sort of readjustment many of us who witnessed the events went through. He didn't lose any friends or family, didn't get injured - he witnessed it. That makes him unique amongst about 150,000 other people, I guess.
