2022 Baltic Sea Cessna Citation crash

Flight path map

The aircraft, which was approved for operation with one pilot, took off from Jerez in southern Spain.[7] According to reports from Bild, the pilot reported a cabin pressure problem shortly before ATC contact was lost. The Cessna 551 Citation II was flying at 36,000 feet (11,000 m) at the time.[8][9] Shortly after its entry into French airspace, around 14:25 UTC, the Cessna was intercepted by one Dassault Rafale, scrambled from Mont-de Marsan air base. A second Rafale from Saint-Dizier air base took over the interception. The Cessna was continuously followed by the French Air Force until it reached Cologne, around 15:57 UTC, when the German Air Force took over.[10]

Two German Eurofighter Typhoon jets were scrambled from the Rostock-Laage air base at 16:15 GMT to contact the aircraft crew and were unsuccessful. Shortly after Rügen, the German fighter pilots broke away at 16:50 GMT.[7] The plane entered Swedish airspace, where it flew south of Gotland and on towards the Gulf of Riga.[1]

A Danish F-16 fighter took over the escort of the ghost flight. Later, the Danish Air Force said they could not see anybody in the cockpit after intercepting the plane.[7] The Danish jet pilots witnessed the plane going into a downward spiral and crashing 37 kilometres (23 mi; 20 nmi) off the shoreline of Latvia, far beyond the outer edge of the Latvian territorial sea, at around 17:45 GMT.[9]

The aircraft involved in the accident was a 43-year-old Cessna 551 Citation II built in 1979, with manufacturer serial number 551-0021, registered as OE-FGR. The aircraft was powered by two Pratt & Whitney JT15D-4 engines and did not have a flight data recorder.[11][12][5] Since July 2020, it was owned and operated by GG Rent.[5]

Reportedly, four people from Germany were on board: Karl-Peter Griesemann (who has been confirmed as the pilot of the aircraft), his wife Juliane, their daughter Lisa (who also carried a pilot's licence), and her boyfriend Paul.[13][14][15][16] Experts have proposed that the drop in pressure likely caused the pilot and passengers to lose consciousness, as seen in the 1999 South Dakota Learjet crash, the 2000 Australia Beechcraft King Air crash,[17] and the Helios Airways Flight 522 crash. The aircraft's operator was GG Rent GmbH, based in Bergisch Gladbach, located to the east of Cologne, Germany.[18]

On 6 September, Mayor of Cologne Henriette Reker commented on the Griesemann family's misfortune and offered condolences.[19]

According to the Latvian Maritime and Air Rescue Centre, parts of the plane have been located. The Swedish Stena Line ferry Stena Urd was asked to help at the crash site.

Swedish and Lithuanian helicopters flew around the crash site for several hours but did not find any survivors or bodies, said Lars Antonsson at the Maritime and Air Rescue Centre.[20] Johan Ahlin from the Swedish Maritime Rescue Agency told SVT that the emergency services discovered traces of oil on the water and smaller pieces of debris.[7]

On 5 September, the search for the plane debris is underway in an area of about 6 by 6 kilometres (3.7 mi × 3.7 mi; 3.2 nmi × 3.2 nmi) where the sea depth is around 60 metres (200 ft).[21]

On 5 September, a total of 11 plane wreckage parts including seats had been found, and shortly before midnight, human remains were found and transported to Ventspils by the Latvian Naval Forces.[22][23][24][25]

On 8 September, further investigation of the accident was taken over by the German Federal Bureau of Aircraft Accident Investigation.[26]

According to the provisional report, everyone on board the plane, including the pilot Griesemann, became unconscious shortly after asking a Spanish air traffic controller for permission to descend due to problems on board.

The aircraft continued to fly on autopilot until it exhausted all of its fuel and crashed into the Baltic Sea.[27]
