Flight measurements were made of the pressures on the horizontal tail surfaces of a typical propeller-driven pursuit airplane during stalled pull-outs at high Mach number. The results indicated that the load distribution during the pull-outs was considerably different from that prescribed by air-load requirements at the time the airplane was designed, and that large tail-load increments were caused by buffeting air flow over the tail as the wing started to stall.

Data are included which were taken in a pull-out made without exceeding the design maneuvering limits of the airplane, but in which, due to compressibility and buffeting effects not considered in design criteria, a relatively severe failure of the horizontal-tail structure occurred.
