Melchior sent me a property dump of the YF-23 in the wacky superthrust

state.  The only really obvious problem was a giant negative engine
RPM, which happened because of a lack of clamping in the engine code
combined with the YF-23's ability to actually reach speeds near the
engines _vMax value.  It's not clear to me that this will fix the
superthrust issue at high AoA's, but it's an obvious bug nonetheless.
