> With 9/11 I seem to remember one of the impacts only being seen from the explosion, but you couldn’t see the plane itself. Maybe that was the second one?
There is an archive of several news channel and their coverage of 9/11 at https://archive.org/details/911/day/20010911#/. Some of the news channels had better viewpoints and saw the second plane hit on live footage [1]. The NEWSNW channel has a very solid view of the second plane as it hits, which causes the reporter there to react mid-sentence. Note that's the live coverage; since there's so many cameras pointed out the towers by that time, there's several different angles of the actual moment of impact (although most news channels were focusing on the views that best showed the damage at the first tower when it happened live).
There's only three known recordings of the first tower being hit (the best quality one being from someone shooting a documentary film who heard the plane, looked up with the camera, and recorded it as it hit). The hit of the Pentagon is only recorded by a security camera, where there is but one frame with part of the plane being just barely in the view before the impact.
