There was at least a third.

The outcomes were: JAL 747 flew into a mountain with 520 people dead, 4 surviving. It is suspected that there would have been more survivors if rescuers had shown up sooner. The United DC-10 had over 100 dead and less than 200 surviving. The whole flightdeck crew among the survivors.

The third case was DHL A-300 shot down in Baghdad. The crew was unhurt.
And it seems they did lose flaps. A big disadvantage of United DC-10 was that they had to make fast, flapless approach. Whereas the DHL A-300 had the advantage of being shot down in dirty configuration.
