The present invention generally relates to methods and apparatus for improving top drive operations. A method of ensuring safe operation of a top drive includes operating a top drive, thereby exerting torque on a first tubular to makeup or breakout a first threaded connection between the first tubular and a second tubular. The method further includes monitoring for break-out of a second connection between a quill of the top drive and the first tubular; and stopping operation of the top drive and/or notifying an operator of the top drive if break-out of the second connection is detected.
