Go around.

Well, let's play the devil's advocate... What if you can't go around?
(E.g. because of engine failure or in a glider). I mean, I understand
why you don't want to deploy spoilers if you're below minimums or if
you're flirting with stall speed. But if you're well above minimums,
with no risk of stalling, I don't see any reason why you shouldn't use
spoilers to bleed the extra momentum/altitude. The only disadvantage
would be that the final approach will be steeper and thereby would not
have the elegance of the perfect glide slope. But that's seems to be
more a matter of taste (and possibly performance) than an actual
safety issue.

This paragragh has several misconceptions as it relates to the OP.
First, An engine out missed in a DC8 or even a two engine jet is
doable and it is practiced all the time in the sim. Spoiler usage in
sailplanes is a completely different kettle of fish and it is normal
to use them into the touchdown in most ships. The crash discused in
the OP happened many years ago and it has been standard in the
industry as long as I can remember (I go back 20 years) to be on
glidpath, on speed, and fully configured with the landing checklist
complete by 1000 AGL (An exception to this is that in VMC you dont
have to be on speed but you must be slowing). No Ifs or Buts. The use
of spoilers below certain RAs and past certain flap settings is
prohibited in the Boeing products and you would be hard pressed to
find both a captain and fo who would ignore operating limitations. So
its not just a mater of taste.

. If there truly was a physical reason why
spoilers should not come out in the air, it would have been an
engineering requirement to systematically disable their mechanism
unless, say, the gear is down and the wheels rolling.

Actually, this is the way it works. Only some of the spoilers deploy
inflight (Either through the spoiler handle or the Aileron/Spoiler
mixer ). The rest of the spoilers will not deploy until the plane is
on the ground.
