Narrative: This incident was a horrible near miss/mid-air collision; which could have easily end up being fatal. Here is the scenario of what happened.The flying conditions were VFR with unlimited visibility; the air/wind was at 3 mph; flying was very smooth; but the air aloft was somewhat hazy due to distant forest fires. After a brief flight; I returned over the airport at 2500 AGL mid field; flying North to South; and announced on the CTAF (123.00); that I would be descending and returning for a 45 entry to downwind.At no time did I hear any radio calls that indicated any other aircraft in close proximity to the airport; or anywhere near the landing pattern. Sometime prior to crossing the field at 2500 feet; I do vaguely recall hearing someone announce about tracking on the ILS. This happens all the time at this airport; and most people that track the ILS are at least 7 to 10 miles far to the East; i.e. the like to use this airport for practicing. However; when they do go missed approach; it is 'always' announced when they are in close proximity to the airfield; and most pilots are very careful to steer clear of any other VFR traffic in the pattern (which is the typical downwind/base/ final approach). Most aircraft break out of the missed approach mode long before reaching the threshold of the runway; and if they are going to do a low missed approach; will give way to the VFR traffic. After announcing my intentions on the radio; a short time later I entered downwind and announced that I was 'on a short down wind for runway 22; ZZZ.' I then turned base and as I was turning final I clearly announced again on the radio that I was 'now turning short final for runway 22; full stop; ZZZ.'As I came down I was somewhat high and realized that I would be landing a little long; so I crabbed the airplane a tad bit to lose some altitude. As I was nearing the threshold of the runway; at about 80 to 120 feet above the ground; full flaps; 70 mph approach speed; suddenly I was literally sitting on top of a large Cessna high wing aircraft that was absolutely no more than 10 to 15 feet below my aircraft. The wings literally filled my entire windscreen. It felt like we had literally collided mid-air.In all my time of flying; the sight in my windshield was almost surreal; 'What is that???' I literally screamed; 'Jesus!!!.' It was so close that; again; it felt like we had actually collided. The aircraft that flew right under me was moving fast; I estimated about 30 to 40 mph faster than my own speed. As he swept under me he started climbing rapidly right in front of me. I immediately took evasive action; a climbing hard turn to the right; and hit full throttle.I then yelled into the radio (I do not recall the exact words; but the people at the airport FBO sure heard it. 'Who are you? You just missed my aircraft. I am landing at ZZZ.' There was a period of silence. Finally the voice of an older sounding man came on the radio and said words to the effect; 'We (or I) announced a number of times 'way back' that we were on the ILS doing a missed approach.' I then replied; 'I did not hear anybody; and my radio is on.' The other pilot then replied again that they had announced they were going to be doing a missed approach. Then they flew off and there was no more communication. I was not able to get any N number and was too shook up to ask for it at the moment. I then proceeded to do a go around and landed O.K.Upon returning to the FBO; everybody was pretty shook up as well; because they heard the radio calls (I have yet to locate anybody who actually saw the near miss). It was only later that I was shaking and realized how close the miss had been (again; it was all so surreal). The owner of the FBO; said the same thing happened to her at ZZZ when someone was doing a solo under the hood on a missed approach on the same runway; but the miss was nothing as close as this incident. I asked if any of the CTAF radio calls are recorded atthe airport; so we can find out precisely who said what and when; and she said calls were not recorded. I would love to find out who the other aircraft was. She said the only way would be if that aircraft had been talking to Center; or Approach.It seems very obvious here that someone was under the hood watching their needles and not paying attention to whomever else might be in the pattern. They should have easily seen the aircraft in front of them; especially if there was a required safety pilot on board (and looking out the window instead of also watching the needles). IT IS AN ABSOLUTE VIOLATION OF FAA RULES TO EVER OVERTAKE ANOTHER AIRCRAFT IN THE PATTERN; THE AIRPLANE IN FRONT ALWAYS HAS THE RIGHT AWAY (sort of like a rear end auto accident; the guy striking from behind is always at fault).




Synopsis: C182 pilot on a visual approach; experiences an NMAC with another Cessna at about 100 FT AGL as the second Cessna overtook and passed beneath the reporters aircraft then went around. The reporter also went around.
