Hajizadeh said, "There is almost no part hidden to us in this aircraft. We recovered part of the data that had been erased. There were many codes and characters. But we deciphered them by the grace of God."
He said that he was providing information about what Iranian experts had extracted to prove the the U.S. that a successful hack into the aircraft's systems had occurred. For example, he said, "In October 2010, the aircraft was sent to California for some technical issues, where it was repaired and after flight tests, it was taken to Kandahar (in Afghanistan) in November 2010, when a series of technical problems still prevailed."
"Had we not accessed the plane's softwares and hard discs, we wouldn't have been able to achieve these facts," he said.
The U.S. has acknowledged that the Iranians had captured an RQ-170 Sentinel drone, but has also said that Iran would find it difficult, it not impossible, to extract data and exploit any data or technology aboard the craft.
When Iran captured the craft last December, the country said it did so by spoofing the drone's navigation system into thinking it was landing at its base, when it was instead landing in eastern Iran.
