Narrative:

As I came in for my last approachs and turned base to final an ult was ahead and to my left. This ult was headed between the taxiway and the runway, still ahead of me. As I got down to 100 ft this ult flew in front of me, above my position. I saw him pitch up, as if going around, and I landed under him and slightly to his right. The uninvited ult looked exactly like one of ours and I thought it was as I turned final. All ults landed safely, as did I and the demonstration was over. I was low and slow and landed inspite of this ult ahead of me. I looked for him later but couldn't find him. I thought it was careless and reckless for the opposition to do this, knowing that they were not briefed. I did not know till the end that this pilot was in our pattern. I never heard any transmission from any pilots who were not in our demonstration, except for other traffic, someplace else. Our purpose was to show how safe the right pattern was vs the left since ults and other traffic would not mix, in the right pattern. Since everyone followed the rules there were no injuries.
