The CNN/ORC International Poll was conducted nearly two months after the March 8 disappearance of the plane carrying 239 people.
The poll found that 9% of Americans believe that space aliens or beings from another dimension were involved in the disappearance of the Malaysian Airlines plane.
Nearly 79% of Americans think there are no survivors.
Nearly 52% believe that the general public will eventually find out what occurred, as compared to 46% who said that the fate of the missing airliner would always remain a mystery, the poll said.
Some two-thirds of respondents said it is very likely, 26%, or somewhat likely, 40%, that the disappearance was due to actions taken by the pilots or crew members.
Nearly 57% said that terrorists were likely involved in the disappearance of the plane.
Nearly 51% said that the plane, or its wreckage, is located in the Indian Ocean, but 46% said the plane is somewhere else, far from the search site.
Only 26% of Americans said that the Malaysian government has done a good job managing the search and providing information to the general public.
