Actually, that's true about the 9/11 attack -- the simplicity was exploiting the vulnerability in SOP of aircrews cooperating with hijackers and opening cockpit doors. The airlines and passengers mitigated these vulnerabilities all by themselves, without any help desired from or needed by the TSA or any other USG agency.
