Worn one a few times in the past, but not often. The Med Crew advised me to wear one. It really didn't interfere with any part of the flight operation.
Been in the HAA sector 30+ years and appreciate the Med Crew taking care of me when the situation dictates. When it comes to aeronautics, they implicitly trust me...When it come to the practice of medicine, I implicitly trust them. It is as complimentary and respectful of one another and the knowledge each of us has, as that.
Rhetorically, why the melt-down over an N-95 particulate mask?
