That's a pretty shocking photo. Usually, if pilots eject, the ac ends up in a fireball. To have the air frame that intact after an ejection suggests that the pilots had control of the aircraft but might have lost the engine. Hopefully, it would have been trimmed for level flight and when they ejected the aircraft just descended until it hit the ground.
Since the USA sold a bunch of Skyhawk's that we used in the Training Command to Argentina in the early 90's I wouldn't be surprised if I flew this very same TA-4 as a student. Just for the record, it wasn't dented when I returned it.
We had a pilot in our squadron take a vulture strike to the side of his canopy in Florida. Knocked him out. When he came to he saw all of the blood in the cockpit, thought it was his, and he ejected. The aircraft (also a Skyhawk), kept flying around the Florida panhandle for 18 minutes by itself. We called him Premature Ejection (PE for short) after that.
