I think there might be only one piece of footage in existence of the first plane flying into the North Tower! Even that was amazing to have been captured - just some firemen recording some random job in the street and the guy holding the camera happened to hear the plane flying low so looked up with his camera.
There is actually a really good film that includes this.
Two French men were making a documentary about NY firefighters, they were following a rookie in his first weeks or months.
They were not having much luck because every shift with the rookie there was nothing exciting happening, just false alarms or checking for a gas leak.
Then 9/11 happened. The rookie was left in the fire station with one of the brothers while the other was out filming with the crew and of course the crew were diverted to the WTC.
It is well worth a watch as the documentary they started making is not the documentary they ended up filming.
I'm sure it will be available somewhere as the anniversary is this week.

I started uni in 1998, but I was in my 30s so I did have a brick mobile phone. But that was a contract i'd had from when I was working. Most students only started to get phones when pas you go came in.
I was also at a uni with lots of Deaf students so I think uptake was faster due to text messages.
I was quite a techie though, I wrote my first program in the early 1980s (I took O Level computer studies, the school had one computer and that was for us to use not staff).
I remember watching fellow students head to the library when we had a new reading list, I headed to the 'audio visual' room and reserved my books electronically.
