No - a drone did not hit a Mexican airliner. NTSB found that the radome has not been fitted correctly. No drone was involved (I can't post links it seems so you'll need to Google it yourself).
No drone has ever collided with an airliner.
I totally agree that no drone was present in this Gatwick event. Our report can be seen on our Airprox Reality Check website (It is 2019205 - the third one down under October). Again - I can't post links so you'll need to Google it.
