Or the moth stuck on the head of a pin just about the Middle Marker...
I flew one in Dallas at AA, the same model was used by 5 differenet simulators, you had to "request it" prior to flying the approach, or you did the missed.
The camera actually pointed straight down at the model, there was a mirror at the bottom, along with a safety switch. Go too low on an engine out go around, that switch touched the model and BANG you went backwards. Had some co-workers just about lose their lunch on that one.
Great picture btw.
