Sunderland Riddle
Understand that stores such as mines and depth charges were carried in the hull.
What was the mechanism which sent the stores to the wing hard points from which they could be dropped in a hurry - eg soon after sighting a U Boat.?
And a big accolade for anyone who can describe how the Sunderlands were reconfigured/rebalanced with the fitting of a heavy gun turret down the back end.
