This is the story of Scandinavian flight 751. On the 27th of December 1991, a Scandinavian MD 81 was to fly from Stockholm Arlanda airport to Warsaw Chopin airport with a stopover at Copenhagen. The plane landed at Stockholm at 10 pm the night before after an almost two hour flight from Zurich through the chilly air of Sweden. On the morning of the 27th at 7:30 am the mechanic who had to get the plane flight ready found that the underside of the wings were all iced up. If the underside of the wing were to be iced up that means that the upper side could be iced up as well. He gets a ladder and feels the forward part of the top side of the wing. He finds no ice but he does find slush, a mixture of water and snow. He then went on to check the engine inlets for ice, the temperature was hovering around freezing or 0 degrees celsius. So these checks were important. By 8:30 am the plane was fueled with 1400 kilos or 3000 pounds of fuel, the captain in consultation with the mechanic decided to deice the underside of the wing in addition to the upper side. Ice on an airplane's wings is increadibly dangerous as it changes the shape of the wing and that can lead to the wings generating less lift. At takeoff a plane needs all the lift that it can get. The mechanic started de icing the top of the wing first, he sprayed de-icing fluid on the top of the wing twice just for good measure. The 85 degree celsius or 185 degree fahrenheit fluid should have cleared the wing of any ice it may have accumulated.

With the wings now clear of ice and snow the pilots proceeded with engine start. The captain asked the mechanic “Good and clean under the wings?” the mechanic replied “Yes there was a lot of ice and snow, now its fine, it's perfect now” With the ice cleared away and the pre start checklists done the pilots taxied the DC9 over to runway 08. With the plane lined up the captain opened up the engines and the plane was on its way to being airborne. The plane lifted off at 8:47 am local time and almost immediately the passengers heard something in the back of the plane. It sounded like a low hum. But the sounds didnt stop, the sounds grew worse, they could now hear bangs and the aircraft seemed to be braking. The pilots could see that the right engine was struggling the first officer called out “I think its a compressor stall. '' The captain pulled back power on the right engine, but that did not solve the issue. The plane was climbing throught 2000 feet of altitude as all of this happened. 64 seconds after the plane took off the left engine began to surge. 51 seconds after the first sign of trouble the right engine had failed.two seconds later so did the left engine. The plane was at 3200 feet and was doing 196 knots. With no engines the screens in the cockpit died, the crew relied on a small backup artificial horizon in the cockpit. 13 seconds after losing all power the crew got a warning for fire in the left engine, they activated the fire suppresor in the left engine. A passenger flying on the plane was an offduty SAS captain seeing that the plane was in trouble, he hurried to the cockpit to assist in any way that he could. The off duty captain was tasked with bringing the APU or the auxiliary power unit online. The first officer let stockholm control know of their problems and ATC let the crew know that runway 01 was available for them to land on. The captain says “prepare for on ground emergency” This was the cabins cue to brace for an emergency landing.

At 1300 feet above the ground the captain started to extend the flaps slowly. The assisting captain confirmed that the flaps had been fully deployed, At an altitude of about 900 feet the plane broke through the clouds. The captain saw a field far off to their right but it was too far away and there was no way that theyd reach it with the altitude that they had. He saw a field
