Registration marks on the wing of a prototype Concorde.
A surprisingly common sight in Winnipeg – houses raised up while new higher higher or deeper basements are built underneath. The ground is an aggressive clay that leaves many houses heaving in strange directions.
Thanks for the photos, Phoebe
I posted pictures from a similar ‘plane from Duxford a while ago. This one is from PIMA and shows the hinge that allows the wings to be swept back for storage on an aircraft carrier. There is a single axis hinge and one flap that falls down to accommodate the movement and then come back together with a continuous aerodynamic surface. It must have taken some working out – I wonder if this was done through drawings or models?
