The pilots and all those monitoring these sightings visually and with instruments including radar could not ID these as ordinary aircraft?? Does not seem likely. Surely the most advanced navy on earth has the capability to ID aircraft in its proximity. If it can’t...
Long retired but I was a pilot for a commercial carrier.
A couple of times when we encountered objects that appeared unnatural in shape and movement (usually over water), they could be plainly seen by us but wouldn’t show up on any flight operations/ATC scopes!
