had exactly the same thing happen 2x, maybe 10 min apart: departing ORD on UA's first 777, about a week after it entered service in June 1995 ... after the second one we went back to the gate; maintenance came out to the jet and reset a fault indicator on a box in the avionics bay, and we proceeded on to DEN

the most memorable go-around was an Allegheny Convair 580 at ITH in Mar 1974: the tower wasn't staffed on Sun morning, so ELM Approach (about 30 miles away) cleared us for a visual approach ... as we rolled out of a descending right turn onto final, the captain pushed the throttles forward, raised the nose and flaps, and basically completed a 360-degree turn at pattern altitude ... as we came back around I saw a Cessna 150 turning from the runway onto a taxiway; turned out the pilot was one of my ROTC classmates

I can't count (more accurately, can't begin to recall) how many RTO and go-around test conditions I experienced as either an analysis engineer or Test Director during my three years at Boeing Flight Test; again, though, there's one GA that stands out in my mind, from a 767-200 certification test flight at Moses Lake WA (MWH) in Jul 1982 -- the test condition starts at an altitude of 50 feet with throttle push, followed by a simulated engine failure at full power, which of course induces a not-insignificant roll; as TD, I was in the first observer's seat directly behind the pilot, and for a brief instant my view out the 3L window was almost entirely of the ground
