Absolutely no expert and fishing in the blind - question to the expert: Shouldn't you use spoilers and thrust reverse in Midway in wet situation given the relatively short runways, history, proximity to public streets etc...? Don';t see them on the photos deployed...

I know, it says:
The thrust reversers and speedbrakes were not deployed according to Southwest Airlines’ procedures. Speedbrakes were fully deployed 16 seconds after touchdown and the thrust reversers were deployed 19 seconds after touchdown which resulted in insufficient deceleration during the initial portion of the ground roll for the aircraft to stop before the end of the runway.

But a) why do I not see any on the pictures, unless thy were stored again but that seems not SOP to change settings in the cockpit after you crashed and b) why is it SWA SOP not to use those at MDW - didn't they learn?

I think the notable thing is that with 27,000 hours combined experience in the cockpit this can still happen. We should all take note particularly regarding reverser and speedbrake position on short runways. Interesting that lightning should strike twice as well!

Well, I (non native English speaker) read it that the fact they weren't deployed was not according to SWA sop.

I read it that way too - It's quite ambiguous language for an accident report!

I read it to be as in they didn't deploy them on time (took them 15-ish seconds to do it)

Check the books! Manual brakes stops 500 ft. shorter than MAX AUTO brakes. Why wait on the auto brakes!
