50 years ago we sometimes had an hour plus holding into Heathrow, partly due to SOP of being fully established in landing configuration and speed by 3,000 ft..continuous descents and maintain 180 knots to the marker were introduced which many found unable to comply with..eventually this was accepted as was land after clearances. At the same time others could manage the Kai Tak and Gibraltar round the rock avoiding smoky joe approaches. Education and the introduction is wide bodies changed things.
Fortunately my next flag carrier operated into a lot of unusual places where electricity had only recently been discovered and by extensive training with high standards and a sensible approach to SOP we were able to operate into airfields which some would say was imprudent.
Sadly, imho, training and piloting skills along with common sense have been replaced by automatics, acars and the replacement of “captaincy” in some airlines.
Watching the video presentation I agree that nobody did anything wrong..it’s just the obvious evolution of the system with the loss of the skill set to fly an aircraft manually and look out of the window..maybe a few minutes on oxygen during descent might have helped but that is probably verboten now.
