I took a look at the third pilot on the list... Captain Bruce Cartwright of Delta Airlines.
See his obituary here:

He was 73 years old and had Alzheimer’s. Where’s the mention of any vaccine?
So far, two of the 3 I’ve seen are RETIRED pilots.
Just think whatever your professional career affirmative-action government bureaucrat/educrat religious leaders tell you to think.
