Obsessions and Interests

So I've been umming and ahhing over whether to post here about my special interest. I am obsessed with disasters and accidents of any sort, but mainly air crashes/accidents. Related to this is my overarching obsession with 9/11. I can quite happily watch any episode of Air Crash Investigation(MayDay in other countries), even though I have watched them all many, many times before. My husband is very patient putting up with this, especially as I have a tendency to tell him what is going to happen and why the crash happened.

I watch any and all documentaries about 9/11 (except conspiracy theory ones; I cannot even get through 10 minutes before I'm basically screaming at the TV). I don't like to go to sleep in a silent room, and usually have a documentary or NIST FOIA footage of 9/11 on. I came to the realisation last year that I'm not interested in the human side of either 9/11 or disasters, but rather the mechanics iykwim? So in terms of 9/11, things like how fast the planes were...
