#1. When you shoot the vertical stab off a 262, the horizontal stab and elevators remain on the plane, although hovering in space attached to nothing several inches above the top of the rear fuselage.
#2. Hits on the HORIZONTAL stab will knock off the vertical stab, while leaving the horizontal stab and elevator intact.
#3. It appears that 1x20mm hit on the horizontal stab will knock the vertical stab off the plane. OTOH, 6 or 8 13mm and 20mm hits right in the cockpit won't kill the pilot.
I got this on film if you need it.
