Logic..............
Logic is leading where nobody would have gone:
1- Because of lack of security at airport, we have to embark anykind of Airmarshalls who are not under captain authority...
2- Because they may fail in stopping terrorists to take control of the plane with the risk of thousands dead, we can now be "escorted" by any fighter of any nationality, whose mission is in fact to kill us our crew and passengers if we drift from the flight plan.
It's only a matter of time before the real thing happens
Comprehensive insurance will pay your widow, or maybe this will be covered by concerned government.
