Undercover operation reveals TSA failed most tests at United States airports

The failure rate of security test was "in the ballpark" of 80 per cent, a source close to the investigation told ABC News.

According to NBCNews.com, the Department of Homeland Security sent undercover inspectors through several USA airports to review the performance of TSA officers, the screening equipment and their procedures.

The report comes just two years after a similar operation found the TSA failed 95 percent of its tests.

Twitter users questioned whether airports should still use TSA and lamented the security process.

The report on covert testing by the Office of Inspector General was delivered Tuesday, Nov. 7, in a classified briefing before the House Committee on Homeland Security.

The program started in July and has slowly expanded across the country to 280 airports in response to what the Department of Homeland Security calls increased threats to aviation security.

In the public hearing on Capitol Hill this week, members pushed for new scanning equipment, which creates 3D images of bags, which can help TSA identify potentially threatening items.

After results of the undercover screening tests were revealed to congress, eight classified recommendations were made.

"We take the OIG's findings very seriously and are implementing measures that will improve screening effectiveness at checkpoints", TSA Administrator David Pekoske said in a release.

Pekoske said that "to invest in the CT technology requires funding above what TSA now has", but the agency wasn't on the path to CT development at checkpoints when the budget was developed, so the program wasn't reviewed for investment.

'The security measures affect all individuals, worldwide passengers and U.S. citizens, travelling to the United States from a last point of departure global location, ' said Lisa Farbstein, a spokeswoman for the TSA.

"These measures - some of which are noticeable to passengers and some of which are not - include enhanced screening of passengers and electronic devices, and heightened security standards for all direct flights to the United States from overseas airports".
