Not really: this time you said 100 yards. Last time you said 200 yards. To me it looked like around 25 to 30 yards, max, from where he was at his low point to the tops of the heads of the people standing around uselessly gawking.
If he had been armed, he'd have had a good chance of hitting key persons, if not Trump, then John Kelly or others.
I was astounded at the inaction, including by the snipers on the roof visible in one of the videos at the link. They should have had weapons with telescopic sites aimed at him and tracking him.
Yes, he got closer to the people in front of the building that I first thought.
But President Trump was inside by then.
Notice the people outside, looking at the paraglider, are looking away from the building. The guy furthest out front is almost underneath the machine.
