So they were at ~5,000 feet doing, what, >200mph? Something about the size of a large pizza passed down one side of the aeroplane. Even if visually acquired at the earliest possible stage it would have been visible for 2-3 seconds, and as a detailed view perhaps half a second? Yet in this time the crew positively identified it as "a drone".
They then say it passed over the wing, 20m out from the fuselage, and "over the tailplane". Aside from the detail that the A320 tailplane semispan is under 7m (so it went nowhere near the tailplane) mhow the heck did the crew know this? How much of thie wing is visible from the pilot's seat? Or are we expected to believe that said crew opened the window and stuck their heads out to watch?
The whole report is clearly dubious in the extreme.
