I thought that with a 1-26, that's actually how they operate even at 0 wind
:-))))

If the cross wind is straight across the runway and strong enough you can
crab 90 degrees and land vertically, like a helicopter. Though I've never
actually done this I have "parked" a 1-26 above the middle of the field at
1,500 feet and descended vertically to pattern altitude before putting the
nose down and proceeding. Of course, folks "park" in wave all of the time.

Why would you NEED both in a strong

and why.



You don't NEED both. You can achieve the needed angle between ground
track
and direction of airspeed just by using crabbing, since there is no limit
to the angle you can obtain by crabbing. However if your mind is to use
slipping there is a limit to the angle that can be achieved by slipping,
if you think the thing to its extreme, when slipping with a 90 degrees
bank the useful angle is reverted to zero, so there is a maximum
somewhere.
So if the crosswind is so strong that the needed angle exceeds this
maximum,
even if you want to use slipping, you have to add some crabbing, in this
sense slipping and crabbing are additive, i.e. the resulting angle may be
due partly to slip and partly to crab if both are used.
