Northrop Grumman Corporation patented a system for landing a tailless aircraft in a crosswind. The patented steering system is used to steer the nose wheel. First, the nose wheel is disengaged upon impact with the runway so that it is free to castor; and thereafter, it is engaged after a specific time period after the nose wheel impacts the runway such that the nose wheel is steerable.
