i have to disagree with the statement of the howling sound a mustang makes in a dive. it's coming from the rad intake on the bottom of the fuse. the guns are way to small to make such a deep sound. if the guns were at fault , you'd hear i very high pitched whistle not the deep howel. i was at a show where three mustangs were doing that all together whoa !! another reason the noise isn't coming from the guns due to high angle of attack is the wing would most surely stall if that was the case. that's my 2 cents
