Hotel Tango
I don't think its about absent minded senior moment pilots I know some 70 year olds who still fly non AOC commercial OPS in jets who are very knowledgeable and on the ball
It maybe that they were taught in a different Era? It maybe that with such vast experience comes complacency?
It maybe that the motivation and keenness of young pilots has mellowed somewhat so there is a reluctance and lack of hunger to take on new stuff or not to be quite as focused as their younger counterparts if its true )
