>>The important 1 that you MUST REMEMBER! Again MUST romember. Is to put the pin into the nose gear. Otherwise CRUNCH.<<
In the NWA incident at SIN a Boeing nose gear pin was not available for some reason. A locally modified Airbus pin with a handle welded on it was used to pin the nose gear. When the hydraulics were powered, the nose gear door cycled, catching the handle, pulling it out. A guy under the plane saw what was going to happen next and escaped before the inevitable occurred.
