OK, you are strong. Stick force to get 9 Gs at 600 kts at 1000 ft was
over 50 pounds. Not many good reasons to be doing that in ACM since
the vertical was best for the F-4. The F-4 had a rare but
unrecoverable flat spin mode. In this mode we tried everything
including special anti-spin chutes and still never recovered one. Most
of these flat spins were entered from very nose high, slow speed high
yaw maneuvers, like trying to kick the nose down from a very high yo
with the rudders. Drag chutes, even anti-spin chutes just streamed
above you. very gentle spin rate and low altitude loss per turn but
just plain unrecoverable. We lost at least four F-4s at Pax learning
about this mode. MacD denied it even existed.
