Investigators of the airplane crash that killed 96 people, including Polish Presdient Lech Kaczynski, said Wednesday the black box has indicated there were non-crew members in the cockpit.

"The voice of one of them has been identified exactly, the voice of the other, or the others, will require additional information from the Polish side," said Tatyana Anodina, head of the inter-state air committee that investigates crashes in the region.

The identities of the non-crew voices were not given.

The probe has also revealed that air traffic controllers at Smolensk airport in Russia twice warned the crew that heavy fog and low visibility meant they were not ready to receive the flight.

More than five weeks after the crash, no concrete conclusions have been made, although an act of terror, technical failure or an explosion have all been ruled out. "The engines worked until the collision with the earth," said Anodina.

Kaczynski, his wife, and other Polish dignitaries were on their way to a memorial service at Katyn, near Smolensk, for 22,000 Polish officers and troops who were killed by Soviet forces 70 years ago.
