Dumb Question
On one of the pictures that Landing-24R has put a link to, the is a clear image of the 737 tail section. Looking on the side of the fusilage just under the front of the tail plane is what looks like a slot with further back at about the midpoint, what could be a hing. Am I right in interpreting this as an all moving tail plane ? If so, I never realised that large transports had them . . .just little pipers.
