You know, on the day of the 5 hour ATC delays, planes held at the end of the 10s for 3-4 hours waiting to take off, with some returning to the gate and departing 5-6 hours after initial push, and the 19s, 28s, and 10s were being used for take off at the SAME TIME because the winds kept shifting at one point. Does that sound normal? JFK and the other major US airports have similar delays when strange winds narrow them down to 1 runway or several configuration changes. Just one of those days, average ATC delays over 2 hours are rare at SFO.
Hell, the Lufthansa 747-8i, Virgin Atlantic A340-600, SAS A340-300, British Airways 747, ect all went off the 19s that day. Very rare to see that, usually even if the 19s are being used for departures, most heavies take the crosswind off 10L/R. Not an option that day, you sat by the 10s for hours until you could go, or blasted off over the Millbrae hills. At 430AM, the Hawaii flights were arriving and there were still United and Alaska planes between the 28s holding for gates! Not a normal occurrence, by any means.
