15:52-15:57:  Genie Lift moved from parking spot just outside the Control Room exterior door down to the Staging Building lower parking lot.  The engine was clearly heard in Control Room and then when it rolled on the rocks it was a little louder.  IMC remained locked (Jeff K mentions since we can hear it, it's high frequency and the suspensions can therefore ride through it.).
