After this attempted murder-suicide by a passenger on a “third level” air-carrier (posted below) it’s going to be interesting to see if access to the front seats (and the flight controls) on smaller aircraft is modified. Sometimes, aircraft with as few as three passengers (plus the pilot) are used by lower level operators and charter companies – especially in lower-traffic areas. If these operators were to be forced to block off that front seat and limit access to the pilot, it could have a huge impact on their viability.
Where’s the appropriate line for making air transportation safe?
