Further to the S61 NS stuff, during the 70's we shuttled the bears to and from work in the Brent Field almost daily with 212's, average hop <2 minutes. Shift changes were 0600 and 1800, anything up to 4 x 212's moving 11-13 pax at a time. Worked well, and all loading was at ground idle.
Not a daytime flight hour logged mid winter, either
