Hello. For reference, the part in question is at 5:56 in that video. That little edit has so many weird moment, it's really a 8:00 weird moment. My favorite scene is at 2:50. Never, ever, ever talked about, huh-uh.
This is perhaps an interesting enough topic for its own thread and IMO a good question. He says with every fiber of his intent that the plane was and did everything the official story requires, but from a North of Citgo path. It's an impossible combination, but it's the "only one thing that’s irrefutable, that isn’t me guesstimating." So they pick and choose, since he won't. Of all NoC witnesses, he's the one they pestered about the discrepancy rather than downplay it.
Therefore, Ranke mentions at 5:56 the "official story" pole locations and sets up a never-repeated feat of mental gymnastics. Lagasse can't abandon NoC now without saying something really dumb. So he does, and insists "nothing happened over here," where light poles were knocked across the road and into at least one car. He clearly indicates pole and cab troubles further north where nothing happened. He's in his own little universe here.
Oddities: He told CIT he didn't actually see these poles being impacted, but their downed location matching where he saw the plane was enough to deduce on.

Earlier, when talking with Dick Eastman back in 2003:
Eastman:
2. You did not say whether you saw the poles being struck down. Am I right
in assuming that you did? Did you see how high on any of the poles contact was made?
3. Can you recall seeing what part of the plane struck any of the poles?
Lagasse:
Question #2.... near the top....yes I saw the plane hit them..granted at the
speed it was traveling I cant be 100% sure of exactly where on the
poles...but I did remember a black and orange cab that was struck by one of
them
Question #3 Wings....there was composite material from the wings in the
area around the poles that had been struck..the fuse could have struck one
of the poles as well.
Also, when Craig tries to confront him with the "official story" with a plane south of the Citgo, Lagasse asserts there isn't one of those at all aside from the Arlington County After-Action Report, which shows this for the plane's official trajectory:
And for the record, people who love to quote Lagasse's statements about how CTists make him sick, that was said once, as an introduction to eastman in 2003. Since then he's never changed his tune on the impact, but has become softer and more 'helpfull' in tone, and has never backed off giving them the BS they need to craft their geometry problems. He has never said a bad word about the CIT, and Craig proudly posted the Sgt's post-PentaCon-viewing response
here.
So yeah, not a very consistent or reliable witness, to say the least.
