Dave Elfver, 75, talks Monday, Feb. 4, 2019 about the plane crash in his Yorba Linda, Calif., neighborhood Sunday, Feb. 3. He said he was getting ready to go to his friend’s house to watch the Super Bowl when he heard a whining sound "like a motorcycle going a hundred miles per hour." Then, he said, came the explosion. "The whole house shook. I thought it was an earthquake, but the whining sound didn’t make any sense." The pilot, the lone occupant of the plane, and four people in the home that burned, not shown, died. (AP Photo/Amy Taxin)
