The worst thing is for a country to attempt a gradual shift from inferial to metric as is the case in Canada and the UK. Thankfully, the Gimli Glider didn't kill anyone but only because they were lucky. Ultimately, mixing the two systems will kill people; probably has already and was secreted in the media.

Unfortunately, here in the dumbed down USA, the gradual introduction of metric has only led to a situation where the majority now has two measurement systems it doesn't understand.
