Dang... that just plan stinks to say the least. Sorry to hear, Tom, but most importantly glad you are fine. The rest can be repaired / replaced.
In watching your vid, it's clear why #911 Boxster ran out of track and the rear slid into T11 gravel trap. However, #707 should not have been anywhere near the gravel based on line. His apex line looked late to even a school line... except he never turned in... Tunnel vision unfortunately probably set in and he stared at the #911 Boxster until his hands lead him into the gravel too...
Such a shame but again glad you are ok.
Keep racing and keep posting updates
