The cooling duct. It works exactly like a whistle does.

I was always lead to believe it was the gun ports, and only on the D's.   :headscratch:

It's the same thing we have under the radome of my jet: a deer whistle for landing in the Texas Hill Country.   :bolt:

Yes, but airflow across the mouth of those tubes is not 90 degrees in flight. Perhaps turbulence plays a part? I still favor the air duct, because there are Mustangs out there without the gun ports and yes they still whistle.

Mustangs without gunport make the same sound.  Watch a video of Lee flying Crazy Horse.

Here is a good video of P51D making the whistling sound. It seems it happens at certain angles in flight.

its dives and pull ups on the gunports and on several openings more than likely the lower intake and the nose intake. its air rushing over an open hollow area :airplane:
