Statistics v numbers.
Chronus: those ain't statistics; they're barely numbers. Per the article, since 1977, when the FAA allowed single-pilots on certain jets, 107 accidents have occurred with those types, and 67 involved two pilots, 40 involved single pilots.
So, the article tells us, SP ops are safer. Likewise, the Concorde was a safer airliner than the 737, since the Concorde only had one accident (What Mr. Reid means by denominator neglect).
But it gets worse. Even their BS numbers need to be massaged: they included 43 European accidents, while admitting that Europe does not allow SP ops with the same liberality as the FAA. Of those accidents, 4 were SP, 39 TP. So if you toss out the accidents for which the FAA 1977 decision is irrelevant, you get 28 TP accidents and 36 SP.
They shoulda doubled down, and said Euro pilots were ten times more dangerous in pairs.
