A citizen of Armenia died on board a flight from Yerevan to Krasnodar, a Krasnodar International Airport air traffic control services source told Interfax news agency [RU] today.
"Yesterday, the plane crew reported the deteriorating health of one of the passengers on board. Six minutes after the crew's report, the plane landed safely at Krasnodar airport, but by that time the passenger had already died," said the source.
According to the unnamed source, the cause of death, presumably, was a heart attack.
