"Why have there been so many accidents and incidents in commercial aircraft over the years."
Maybe its because there are more than 12 of them flying around .Well sometimes there are 12 not all flying though, well maybe 9 then.
Oh unless you mean the Comet because that took three fatal crashes between May 1953 and April 1954 for BOAC to withdraw its depleted fleet of Comet airliners.
