Only partially true.
On boarding, pilots of commercial aircraft allow kids to see the cockpit and sometimes take the time to give them a little tour. Also, almost all airlines now have the pilot standing in the open door of the cockpit after landing and take the time to address each passenger as they depart.
Airlines have made extra efforts to connect the pilots with the passengers since regulations now require them to be physically separated from them in flight.
The terrorists may have changed the in-flight security rules, but they haven’t changed our humanity nor the airlines recognition of the need to have a connection of trust in our pilots.
