Seriius olycka
Scandinavian Airlines Flight
Scandinavian Airlines Flight , också kallat Gottröraolyckan, Gottrörakraschen eller Miraklet i Gottröra, var en flygning på morgonen den 27 december med SAS-flygplanet Dana Viking. Flygningen startade på Arlanda utanför Stockholm och med destination Warszawa, via Köpenhamn. Någon minut efter starten från Arlanda klockan upphörde motorerna att fungera. Planet fick göra en nödlandning och havererade på en åker norr om byn Vängsjöberg i Gottröra socken i Uppland och bröts i tre delar. Alla passagerare och besättning överlevde, medan 7 personer skadades allvarligt varav 1 fick bestående invaliditet.[1]
Om olyckan
[redigera | redigera wikitext]Efter 25 sekunders flygning började den ena motorn att "pumpa" och efter drygt en minuts flygning (78 sekunder) hade båda motorernahavererat. Orsaken var att en beläggning av klar-is på ovansidan av vingarna bröts sönder och sögs in i motorerna, vilket orsakade ett så kallat FOD (Foreign Object Damage). Motorhaverierna gav piloterna mycket kort tid att förbereda en nödlandning, då flyghöjden var låg, flygplanet var tungt med mycket flygbränsle och täta låga moln som gjorde det svårt att hitta e

Saltsjöbanan train crash
Railway incident in Sweden
The Saltsjöbanan train crash occurred in the early morning hours of 15 January [2] A passenger train started to move without authorization, with only a cleaner on board. It overran a set of buffer stops and crashed into a block of flats in Saltsjöbaden, Sweden.[3] The cleaner was at first suspected of having "stolen" the train,[4] but was later cleared of blame, as the train was found to have started moving because of violation of safety procedures.[5][6]
Incident
[edit]On 15 January , a Saltsjöbanancommuter train crashed into a residential building in the Stockholm suburb of Saltsjöbaden, seriously injuring a cleaner who was in the train at the time.[7][8][9] Travelling through two stations at 80&#;km/h (50&#;mph),[10] the train derailed, running into the ground-floor kitchen of a house.[11] The woman's condition was described as "serious but stable" in hospital.[12] None of the five people who were inside the house at the time of the crash was hurt.[13]
