I owe you all an apology. I was running out the door for a flight when I saw the nitric oxide comments. Being a NICU therapist there are very real concerns about using this modality in a con fined area. However, I did not mean to use the work "Chief" in a derogatory way. It was kinda off the cuff and I did not put much thought into the term. Again, I apologize. Thank you for pointing out my callow comment. But honestly, the point here is nitric, not my verbiage. In any case, safe flying always...
