As the investigation into the mysterious disappearance of Malaysia Airlines Flight 370 focused Wednesday on deleted files from the home flight simulator of the pilot, Capt. Zaharie Ahmad Shah, a host of possible explanations — and conspiracy theories — has materialized.

"Nothing is going to be determined as a fact until we either have a wreckage or an airplane," aviation expert Al Yurman told FoxNews.com. "You cannot make factual statements in an aircraft accident until you have either of those. What's happening now is complete speculation; everything's possible."
