Re delivery to Las Vegas, it's interesting that Lockheed test pilot Elmer C. McLeod also delivered two other new Electra 10s, CF-AZY and CF-BAF destined for Canada, to Las Vegas just a few days after he had done the same for X16020. Source: Elmer C. McLeod flight log book #4, 1935 to 1937, page 10 (dmairfie.ipower.com).
