It is hard to believe that in 2022, we have an aircraft that has outwardly exposed hinges present on the cockpit mechanism? Where did China find the engineers who think that this form of 1950's design thinking is still appropriate?? It's not like this isn't a solved design issue that those engineers could have copied from else where eg Gripen's approach, or Rafales .....
Does feel like the "A" Team worked on the J20 and the "D" team at Chengdu worked on the design... very primitive to see in this day and age ...
