On a LanCile flight from Puera Montt to Punta Arenas severel years ago and prior to 9/11.
A passenger sitting just in front of me was being a real problem with the crew, demaning lunch now, attempting to open the cockpit door and in general being stupid. I was trying to
figure out if I should use a belt to tie him down when 3 pretty good size Chilian men came
back to his seat and forced him to stay in it. When we arrived at Punta Arenas the local police came on board and made him stay in his seat until all had deplaned. Found out later that he was a T.V. personality from Santiago and was high on drugs. He spent time in jail.
Everyone on the flight was very uncomfortable. Now, after 9/11, passengers would become more proactive and strapped him to his seat. I now carry heavy duty zip ties in my carryon
