The former managing director of Szymany Airport in Poland has revealed that the US Central Intelligence Agency used the airstrip secretly for its torture program

The former managing director of Szymany Airport in Poland has revealed that the US Central Intelligence Agency used the airstrip secretly for its torture program.

Mariola Przewlocka told The Daily Mail on Sunday that the agency flew terror suspects into the airport and then to a “dark site” for brutal interrogation techniques.

She said mysterious flights arrived with little notice and several cars with darkened windows took passengers from planes. Anonymous officials paid the landing fees.

According to Przewlocka, airport employees were banned to approach the aircraft.

She claimed that famous 9/11 prisoner Khalid Sheikh Mohammed was also among those who landed in the airport.

“We should not have accepted the flight – there weren’t even any firefighters on duty, which is illegal – but we were given no choice,” she said.

The Szymany airport was also mentioned in the US Senate Intelligence Committee’s report on the CIA torture program.

On Tuesday, the Senate report disclosed that the torture program did not work.

The tactics were more brutal than previously revealed and they delivered no "ticking time bomb" information that prevented an attack.

The report also said the CIA misled Congress and the White House about the harsh methods such as waterboarding, sleep deprivation, mock executions and threats that the relatives of the prisoners would be sexually abused.

"Sleep deprivation involved keeping detainees awake for up to 180 hours, usually standing or in painful stress positions, at times with their hands shackled above their heads," the report said.
