It would be close to impossible. Sorry to break the news, but that's life in the fast skies. That's truly disturbing. I can only hope that airports will find and plug the security holes before something terrible happens. Nor, certainly, are improving other security measures.
TIP is software that runs on the airport X-rays.
TIP tracks how well each screener detects these images so the companies and the FAA will know how well they are doing. Because they'll be getting constant practice in seeing what these dangerous objects look like in cluttered bags on the X-ray, screeners will in effect be undergoing constant training. In addition, they'll have to stay alert because these images will come up throughout their shifts. In addition, companies can monitor how well each screener is doing and determine whether they need retraining in particular items or whether they need to be taken off the X-ray operator job. TIP will also give the FAA objective data to judge how well each screening company is doing.
