Dani. A very strong point to be made. Why are we missing the Pilots' side of things? The a/c is shown, yet the Pilot data is not.
Much of "UAS Procedure" (such as it was at the time), is missing, so observed and oriented or no, the pilot's did not act on UAS, seemingly. What was it they thought was going on?
In the absence of the record, to accuse them is illogical.
