Narrative: We were practicing touch and goes and pattern work. The flow was consistent. I was practicing touch and goes. We had a few short approaches and then on our final circuit doing a regular landing (8th touch and go) we had followed the check list and verified against both the Green indicator light on the Dash as well as the floor indication that the Gear was down and ready for landing. On Downwind we had gear down at 100 mph for Runway 4L. On Base leg out Speed was 90 again verified Green and down. On Final Airspeed to 80 Mph and again verified using on board checklist.We had the power pulled all the way back and were in the flair. Came in to fully touch down and no alarms sounding. There was no horns. A split second before touching down the ATC had casually come on (in a woman's voice) 'XXX go around' as I was about to initiate go around our plane had settled down and prop had made contact with the surface. We slide and I tried to keep the calm and we followed the emergency landing procedures and exited the plane. No one was injured and we had fire crew there within a short minute or two. We were escorted off the runway and into the airport manager's office. The FAA had come awhile later; they asked us what had happened and then the ATC came in. The ATC was trying to tell us we were cleared for a Short approach which we did not request nor did we do. We were on a normal landing and had coordinated to have such. They would not allow us to listen to the playback of the tapes. ATC Live tapes at that time also were pulled from the internet feed. It was a very odd meeting. As the three of us were told that the FAA had to talk to the ATC for a minute and then they had not returned for more than 15 minutes. The Gear had signified it was in the down position both I and the Instructor verified. I as a student am very dismayed and wish to have help in this very unfortunate event.


Second narrative: Had gear up landing with commercial student. Went through check list; gear annunciator was green indicating gear down. But gear was not down.


Synopsis: A Mooney 20E student pilot under instruction landed gear up. Both the instructor and the student report that they followed checklists and that the green gear down indicator lights were illuminated. Additionally; the student reported that he checked the floor indication that the gear was down and that there were no alarms sounding. ATC had instructed a go around just before the propeller struck the runway.
