What would you have done in these circumstances?
Returning to base one day, I informed by ATC as I joined deadside that I was number 2. (ATC is 'Information')
I looked ahead, left and right and towards Base-leg and could not see Number 1.
Turned downwind, and still could not see number 1. Called ATC who confirmed I was number 2. There was no communication between ATC and Number 1.
Fairly late downwind (according to my location), I spotted what might have been Number 1 treating the South East of England as the base leg, and seemingly taking it very slow. In fact, Number 1 was so far out, it could have been a passing aircraft.
Following him (or her) would have extended the circuit still further. I needed to decide whether to turn base and become No.1 or follow them and maintain a ludricous circuit or whether to find another option.
We were the only ones in the circuit at the time.
