After reading the article, i feel that Mas Selamat or other terrorist are wise, just that they use their knowledge in wrong field causing unpleasant feeling for the innocent citizens. They wanted to hijack the plane and crash on Changi Airport which is one of the world busiest airport. If the plan really succeed, i think it'll be a great blow to Singapore because tourism is one of the larger income, the citizens will be in fear and everything will goes wrong! The security must be tight so that Mas Selamat will not be able to escape from the prison again or it'll be the worst nightmare to Singapore if the plan succeed!
