But......
We lose Mark's voice on the NTSB. His leadership there has made fatigue and sleep apnea part of regular NTSB accident review processes.
Having presented at the Kentucky State Sleep Society where we both were able to tour sleep medicine professionals through a working CMV able to show them the practical issues of dealing with sleep apnea in a sleeper berth CMV he is a very valuable resource in improving patient outcomes in transportation.
I do wish him well in his new role.
