After talking with others on my load and review of my video, I'm still looking for some answers. Ok, here's the scenario...1st group opens & secures door, they're a 8 way r/w group followed by another 6way r/w group then our five way (running from mid-ship). Everyone exits with no problem then as the last one diving out suddenly I'm knocked down to the floor by the door, WTF!?!? It happened so quickly I'm still trying to put things together since the video shows to door appears secure up til this point, next thing it shows is me on the floor with the door open only about two or three feet. Since my upper body is mostly outside, I just continued to roll out and away from the plane. Has anyone had this happen or seen anything like this?
