hahaha
forgot about the shoppin trolly,
and yes the major portion of my experience is a very big beefy airplane that fly lotsa people around, coincidently they still have scissor links that need inspecting, and serviceing, replaceing and shimming and have the 'shimmy damper' incorporated into the nose wheel steering actuators
thanks for that the shoppin trolly made me laugh (4 castoring wheels, who's idea was that????)
