There's such a stark contrast between the tone of the early coverage on that day vs what we see with any incident now. While a few of the presenters made mention of the previous bombing at the WTC, there seemed to be a very strong resistance to suggesting it might have been terrorism. I watched another video recently that was a somewhat similar concept, but was longer and bounced from source to source. In that video as in this one it felt like the various people speaking badly wanted the first impact to have been an accident or an explosion from within the tower, rather than a purposeful attack.

Given that the only footage of that first collision didn't come to light until much later and eyewitness reports are frequently unreliable, "we just don't know" was the best they seemed willing to offer. Until the 2nd plane hit, at which point I think the facts spoke for themselves.

That has to be a world record response time. Emergency services on the scene 27 seconds after the first collision!

The team was holding its breath in the countdown to the switch-on after a series of technical hitches, including problems with the cooling system.

The switch-on saw the first stream of subatomic particles - known as Hadrons - circulating in the tunnel. The first collisions are expected in around 30 days.
