One in seven crew members died during the USS Enterprise's five-year mission. A staggering 70 percent of those deaths went to red-shirted crew members. Here's an ELO-assisted highlight reel of the carnage.
Matt Bailey over at SiteLogic last year famously analyzed the mortality rate of red-shirted crew members from the original Star Trek series in context of Enterprise crew deaths overall. A total 43 of the 59 crew members that bought it during the three seasons (of a five-year mission) that we saw were redshirts. That's a 13.7% mortality rate (for a 430-man crew), 70% of which went to the redshirts.
That all seems pretty awful until you clip together a highlight reel of redshirt casualties and set it to an Electric Light Orchestra soundtrack. Then it's just delicious 1960s kitsch but with a body count. Watch it while wearing your official Geekend redshirt, and you'll undertsand.
