Neat! Boeing does metric! Interestingly, there are a couple of errors in the second cited document. In one place meter per second is symbolized as mps and in another as m/sec. Also, hour is symbolized here as hr.
It feels so good to see "Boeing" and metric units on the same page that I won't even fuss at them for that.
