t'is easy to forget - especially when something interrupts the normal. Was landing in Columbia, Ca had someone too close in front of me and did a go round. on return to final - "gear up" alarm let me know that I screwed up . Dropped the gear and landed normally. Wasn't hard to overlook it.
FAA requires that in case of anything that affects the air worthyness of teh aircraft , the pilot must land at the nearest appropriate facility. This LAX us the nearest. Just like Jet blue last year with the stuck nose gear.
