OK, but in this case you shouldn't have written : "F1 in the late 60's and early 70's was extremely dangerous, as this list of deaths confirm:" right above the list, as it clearly implies that they were all killed in F1
And, Scuderia Russ, I am unfortunately not that young, so I was already accurately following Formula 1 when Rindt was killed, and I perfectly remember that Team Lotus agreed that the fixations of the belts to the chassis had broken under the impact. This is not at all to criticize the late Colin Chapman and his staff, but, reknowned for its relentless hunt for saving any useless gram, Lotus had unfortunately an impressive record of various mechanical breakages, especially in the 60s/70s.
