No, it isn't hilarious; it's tedious, mostly due to your posts.
All you do is post juvenile insults, presumably thinking that makes you the "winner" of some sort of argument; hooray for internet tough-guy! You regurgitate stupid shit you read at Popular Mechanic's and post pictures of window washing, as some sort of badge of expertise and "knowledge."
I am admittedly no expert. I only studied engineering up to 3rd year undergrad level, where I then got the bright idea to switch majors and instead got my undergrad in Computer Science, prolonging my graduation date, and eventually becoming a software developer for the last 30 years. But even the basic physics I had to learn during those first years, along with the labs we had to do concerning tensile strengths is enough to figure out that the probability of burning carpet and furniture in #7 could cause a simultaneous failure like seen on video, is essentially zero. Reading the NIST report and its conclusion was beyond laughable. Again, it should be a litmus test for any practicing engineers and if said engineer agrees to NIST, should preclude them from profession.
@Ronws post a bit of his background and his thoughts on the subject of differential calculus, mechanical statistics and momentum, which are much closer to something I would expect to see from anyone with even an inkling on the subject; you are not that.
@Maggot is also correct: You are a one-trick pony, and it's tiresome.
