Speedbird,
I'm curious about your situation when you landed with 2 greens. I was always thought, that if you didn't have 3 greens, you should elect to do a gear up landing. Having said that I'd feel a bit disappointed if I elected to land gear up, only for a subsequent investigation to show that the fault was a sensor switch!
I'm not making a comment on how you handled it; after all it worked out perfectly. I'm just curious if you were thought something else, or if you had good reason to believe that the 3rd leg had locked in place and hence decided to ignore the advise to land gear up?
It's a situation I've thougt a lot about!
