While flying from Las Vegas to SFO on an America West A320 ..the aircraft was packed with a Japanese tour group..i think i was the only westerner on board..anyway to cut a long story short we were only about thirty feet from touch down when the captain slammed the throttles forward and we immediately went into a very steep climb..it was only a routine TOGA but every Japanese person..and we’re talking about 150 people..went into the crash position with their heads between their legs and hands behind their ears..i nearly wet myself laughing
