re: What’s the wildest thing you’ve even seen in person

I was in my loft on the 11th floor in the 12 floor building getting ready for work. I heard a plane go over that sounded funny with a rattling noise. Some seconds later I heard a low frequency boom sound. I figured it was a commuter plane with engine trouble that crashed down town and that's I see it on the news in the evening.

My loft was 12 blocks above the WTC and that was the first jet that hit it.
