Don't ever let this happen to you.
They were doing some touch-and-go's that day. It was a cold day that day so to prevent icing they figured they'd leave the landing gear down since they weren't flying far. But having had experience in a retractable gear aircraft, at one point the pilot instinctively and not-knowingly pulled the lever to let up the landing gear. But on landing they still thought they had it down.
BY NO MEANS am I tryin to criticize them or anything, but they should have heard the alarm going off while they were landing. (There's an alarm in almost all RG aircraft that sounds if you don't put the landing gear down at a certain point during landing). We the viewers can hear it crystal clear. :o
