Many of these changes have come in the form of expanded legislation that seeks to govern the access that suspected terrorist organizations may have to air travel, while others aim to provide expanded security to people who are traveling by air, whether within their own country or internationally. One of the most important developments in international airway security in the the wake of the September 11 tragedy has been the creation of the TSA (Transportation Security Administration). While the foreseeable future for increased air travel security measures remains an uncertain one, it is safe to predict that such measures will be gradually perfected in order to provide safety and security in an unobtrusive manner that most passengers will barely recognize.
