We do. I’ve done a few actual Flaps 5 landings in the 737. Our “classics” were prone to flap issues. I recall having one Flaps 15 landing with alternate extension on a NG. That was a non-event. I mean sure, with a swept-wing airliner, flaps can make a 50 knot difference in landing speed. But the OP tends to fly WW2 stuff and for those, even the B-29, it really just doesn’t that make much difference when leveled against the host of potential REAL problems those pilots had to worry about. Let’s put it this way: If I get to choose between a stuck seat-back recline OR flaps stuck symmetrically at 0, I’ll take the stuck flaps. I know Tinian is plenty long enough for the 30 mph faster landing, but I would probably have to go back to Honolulu to find a decent chiropractor.
