A piece from a fuel cell.
Looks like a piece from the fuselage.
Electronic part.
When we reached the bottom, we decided to check the slope on the other side of the canyon before looking at the larger pieces at the bottom. From the top, we saw what looked like a section of wing on this side.
This is the first part I found on the slope, tag said that it's a longitudinal servo.
Looks like a rib from a control surface.
We were looking for part numbers to confirm that this was an A-4. We didn't find any, but we found lot of pieces that we recognized as coming from an A-4.
Fuselage bulkhead.
AN fittings on the bulkhead.
This looks like a heat exchanger, there was a lot of aluminum tubing wraped on it.
