Nope, no target practice, can't get a gun onboard, as a matter of fact I've been caring a beign swiss army knife everywhere for 4 decades, can't even take it on the plane anymore. I will say that had been a US carrier, your fellow countryman might have found him self facing off against the rest of the male (and maybe female) passengers. We found a role model on September 11. amd learned a valuable lesson.
Having said that, I am always puzzeled by people who throw tantrums, etc. on a plane. I don't understand what sets them off. Why did this guy allegedly flip out as the plane was landing? Every time I read about one of these incidents, I wonder how drunk or stressed out or??? must a person get to behave like this. Maybe I've led a sheltered life
