it a great movie . i love it . i be not to old but i may answer a few question . the kidnapper hijack the vps plane because it be more important then another plane . they do not use a bomb because they want something ( the fellow terrorist to be release ) . if they have use a bomb of course they do not have to tell because everyone would know what to do ( capture them or stop the bomb ) . i totally agree with michael may . maybe if people would not want to see an extra movie then they would like it . it a great movie if you know how to enjoy good film . of course it borrow something from 4 movie but come on it be great the way it be . i like the ace especially the terrorist .
