the world. reporter: but this time, something went terribly wrong. i can see something is wrong. i almost was ready to tell everybody to get out of the way. reporter: wicker and her pilot were in the middle of a maneuver when the plane suddenly plunged to the ground and exploded in flames. they both died. spectators described what they saw. all we seen was the plane roll over and hit the ground. they were too close to the ground. there was no way they would make that turn. just flipped straight over and hit the ground. i went to get my friends and i was like, look at this plane, it s so low. and it just looked like the plane started wobbling and they just got way too low and just crashed. reporter: the faa will now try to determine what happened. officials with the dayton air show suspended the remaining performances as spectators remained in shock. it s terrible. i ve never seen that happen before. you never expect to see something like that happen, and it s awful.
