Skol, the appropriate course of action WAS taken. No one was injured other than himself. As for naivity.......if we had a squadran of F-18's the same action would have been taken. The same thing would have happened in Sydney, London and Washington. This is not the movies. A missile would have been ineffective. A cannon projectile would have gone through a light a/c like it was paper and would have caused far more problems on the ground.
As for "The police say it was not a terrorist attack but who knows the truth?".....I can categorically say that this was NOT a terrorist act.....what exactly do you mean "if this guy was serious"? What do you propose should have been done if all the resources in the world were available to you?
The pilot has been hospitalised and will be able to rebuild his life...no one else was injured. A perfect resolution I must say.
