Just asking - any experts here who can explain the blackened surface look at the base of the tail fin shown here? (it looks burnt to me - but am just observing - not any kind of expert .... just asking the question to gain info.) Also, part of the detachment area has the smooth, rounded look - any explanation? Is that how the tailfin looked before its attachment? (looks like it would be a smooth rounded attachment to some part that fits into the rounded area - ??? like a socket??? Again - just asking.
These photos ought to give many clues. And, surely, chemical analysis of the surfaces of the tailfin at the points of separation would give more info. Welcome any informative replies.
