Someone mentioned, that the incident could impossibly be related to the FTS. So, i got curious what it would look like if the FTS charges fired?
Or if only uper stage FTS charges fired?

Best,
Manuel

I agree. the preceding 2 frames at 29.97 frames a second show it was
well advanced before the next frame catches the explosion. Zoomed in on
the second frame shows nothing visible with this footage. The center of
the explosion seems to be centered

At 01:50 PM 9/1/2016, you wrote:
After looking at the footage I think it is unlikely liquified air is a
contributing factor. I am unsure we will ever know what happened. We
may eventually get the PR story about what happened.

            Looks like you are correct. From Elon himself a few
