BA's superb safety record is evidence that if you are looking for any holes in the operation of jets, then your energies would be better directed to other places!
"No holes in the operations of jets" at BA, sir, [knock on wood], but there are some questionable issues of BA operational judgements, especially that of operating a B744 revenue flight on three engines from LAX to MAN. . . .
But without intent of initiating thread creep, it is common knowledge that at most carriers, the RTO decision is the commander's.
