I was in the approach room that morning, just finishing a night duty, when all the localiser alarms went off! The crew wouldn't have it at first that they had hit anything. The rolling of the aircraft was due to the damage to the undercarriage doors which stopped when they dropped the gear. I thought they lowered the gear quite early on but the report doesn't seem to say this.
We handed over to the oncoming watch and slid off home to bed!!
