In a nutshell, 6 spoilers on each wing, . The 4 inboards on each wing act as flight spoilers, on the ground, all 6 act as ground spoilers. The auto spoilers would be armed for landing if serviceable- it's part of the checklist. When the speedbrake lever motored from the ARM position to the initial detent, the inboard 4 extended, and as the lever carried on aft when the main gear touched down and engines 1 & 3 thrust levers are near the closed position, the ground spoilers (the 2 outers) extended. It may be remotely possible the spoilers were left in manual for landing- very rare. I see nothing very unusual. They were nowhere near 'nearly stopped', trust me. A 747 takes a lot more stopping than that!
Why are people so convinced they have seen a 'cock-up' when they observe something they don't understand? We recently had someone seeing a 737 taxi around on itself, and the assumption automatically was 'the pilot got lost!' (must be Ryan again)
