It is inconceivable to me that anyone would land a jet aircraft without verifying that spoilers are deployed on touchdown. It should be a mandatory callout by the PNF & verified by the PF. If auto deployment doesn't work, for whatever reason, then immediately pull the handle manually. Only when the a/c is firmly on the ground can wheel braking or reverse thrust be expected to properly operate. If this simple routine had been followed here, we would not be writing this thread.
