As you all know, the DC-8 doesn't have slats or Kreuger flaps on the wing leading edge, unlike most jetliners. And maybe you remember one of the differences between the original DC-8-11 and the -12 was that the latter had slots-- inboard of each nacelle, says the Putnam, and it says they were uncovered by something sliding off them when the flaps were lowered.
Do DC-8s still have these? How long and wide are/were they? When did they disappear, if they did?

Hi TimZ, Buzz here. I recall working on DC-8-71's and they have the slots, on the inboard side of the engine pylon.
Perhaps they aren't as effective and sexy as the Boeing version, but they would add a stable airflow on a couple places on each wing, to delay the stall. And the system weighs less than a full span set of drooped leading edges. The DC-8 wasn't made to be a short field airplane like the DC-9.
How long? The inboard ones were about 2 feet long and the outboard ones about 3 feet.
