The classic DC-9 series, 10, 20, 30, 40, 50, had no stick pusher. The first MD-80, of which you recently no doubt saw the tail fall off, via YouTube, didn't have a pusher either. While doing deep stalls, it got into an unrecoverable stall, falling leaf, upon which they deployed the chute.
That's why all MD-80 have stick pushers.
Remember 1979, the year of the AA DC-10 crash at ORD, and the ANZ DC-10 on Mount Erebus in Antartica? Between those two events was an AeroMexico drama that barely made the US news.
They took off from Frankfurt, fully loaded headed for MIA. The Capt. put it in V/S climb, 1500'/min. At 27K ft, the engines could no longer keep up that climb/speed rate, and the A/P began hauling back the speed. The plane stalled at 31K feet, even shaking the cabin panels down, etc. They called a Mayday. The Capt., not recognizing the stall, pulled the power to the #3 engine, which put them into a spiral. He recognized that, and recovered at 10K ft, and canceled the Mayday.
Upon arrival at MIA, the Capt said the flight was normal. The guy doing the walkaround noticed both elevator horns missing, aileron damage, etc., so they quickly wrote up a report. The Capt was demoted to F/O for six months. He blamed the plane for not having a big red STALL light on the panel, like the DC-9, and maybe DC-8 he used to fly.
If they had gone in the drink, that may have been the end of the DC-10 in pax service.
