Aircraft

Our left main tire dropped into a ditch on the left side of the (narrow) runway, which dropped the left wingtip low enough that it caught on a fence post, pulling the plane around into the fence. The propeller struck the fence, coming to a stop after becoming entangled in the barbed wire fence.

Knowing that the propeller governor had been overhauled during the annual inspection the previous month, I suspected a failure of the governor.

As we were seconds away from turning final, we turned to clear extended final approach when a Cessna 172 came across our flight path, narrowly missing us.

As I touched down saw an ultralight landing on the opposite end of the runway. Aircraft was no transponder no radio and was landing against all others in traffic pattern.

My flight was trapped between the top of the Class B at 10,000 feet and heavy traffic at 11,000 feet, resulting in an unsafe condition with no clear solution.

Aircraft Y student pilot confronted Aircraft X pilot after landing, indicating that Aircraft X did not own the airport and was not authorized to instruct other aircraft, with Aircraft X responding that a touch and go is precisely that, not a stop.

I think we are well past the time that it is acceptable for aircraft to fly without a radio.

I can say it was a very busy day and the controllers had their hands full, although the controller losing site of an aircraft that had just departed his runway less than 30 seconds made the situation a little more dramatic than it needed to be.
