Synopsis
Pilot reported they were landing on the SW runway. Another aircraft was landing on the opposite end NE runway. There was a NMAC as the other aircraft elected to abort landing and passed over the opposite direction.
Narrative
Approaching ZZZ after dropping a load of skydivers; I entered the airport traffic pattern on a high crosswind for Runway XX. Subsequent calls were made on downwind; base and final. Neither myself; or the other pilot on board heard any calls from any other aircraft in the area. We are always careful to coordinate due to the glider activity at the airport as well as the VFR traffic when the weather is nice.On short final to Runway XX; I suddenly noticed an aircraft on the opposite end of the runway (Runway XY for them). The aircraft was moving; and heading directly towards us; though it appeared to be on; or just above the runway. We were still on short final and higher. I could not alter my flightpath to the right as skydivers were landing there. I did not want to go left; as that is where I expected the other aircraft to go. In that decision-making moment; I saw the other aircraft begin to climb; and I decided that the best course of action was to go underneath them and continue with the landing.From third party accounts; I believe that the other aircraft did; in fact; make a radio call announcing their position in the pattern and their intent to land on XY. The high amount of wind noise interacting with the headset booms may have prevented us from hearing those transmissions. It is worth noting that we were in contact with ATC during the jump run and in the descent; and did not have an issue hearing them.ZZZ is one of those airports where the runway has a significant slope; and aircraft taking off in one direction; and landing in the other direction; is not uncommon. That was the case on this day. We had departed XY; and were landing XX. The other aircraft was landing XY; but after we landed; a glider landed on XX. The winds appeared to be shifting; but favored XX according to the wind sock. I want to note that there was a radio exchange between our aircraft and the other aircraft that I was not a part of.
Second reporter narrative
My copilot and I witnessed a near mid-air collision on Date at ZZZ. I was flying with a safety pilot doing some instrument flights and we stopped at ZZZ for some fuel. It was a busy day due to the great weather. The gliders were flying and the sky divers were active. The winds favored Runway XY and all of the traffic was taking off/landing on XY. As we taxied to do our run up near the departure end; we heard an Aircraft Y call in that they were entering the left downwind for Runway XY. We also heard the Skydive plane (Aircraft X) announce their position north of the airport and where the jumpers were. The Aircraft Y made the normal pattern calls and called his final to Runway XY. The skydive pilot made a position call; but we didn't catch it. He came in pretty hot (as many do) and called final for XX as the Aircraft Y was touching down. The Aircraft Y called they were landing but the sky dive plane continued to land so the Aircraft Y took off and climbed away. The Aircraft Y passed maybe 75-100 feet over the top of the Aircraft X. The skydive plane seemed without care as it touched down and rolled to their ramp. The Aircraft Y pilot called the skydive pilot and asked why he did that when everyone was using Runway XY (one other had just landed and two of us were waiting to takeoff from XY). The skydive pilot responded; 'that is how we do it here. Get over it!' The Aircraft Y departed the area to the northeast and did not return. We departed Runway XY to the northeast and returned to ZZZ1. The plane that tows the gliders at the airport was behind us and also witnessed the event.
