I wonder if the systems made the pilots think the gear was down, It had been down before, so if some failure in the electronics retracted the gear, the pilots may have presumed it was down without rechecking. Or in their rush to land they had retracted it for some unknown reason yet forgot to put it back down. Or someone selected the wrong switch which retracted it when it was too late to put it back down.
