A Montenegro Airlines Fokker 100, registration 4O-AOM performing flight YM-610 from Tivat (Montenegro) to Moscow Domodedovo (Russia) with 85 passengers and 5 crew, was descending towards Moscow when the captain felt sick and became unconscious.

The first officer took control of the aircraft and diverted the aircraft to Kaluga (Russia), about 70nm southwest of Moscow Domodedovo, where the aircraft landed safely. The captain regained consciousness after landing, was treated at the airport but did not need to be taken to a hospital.

The aircraft remained on the ground in Kaluga for about 9 hours, then “hopped” over to Domodevo airport and arrived with a delay of 9.5 hours.
