In another transatlantic airmail scheme, the Short-Mayo Composite devised by Robert Mayo of Imperial Airways, the modified Empire flying boat was the launch aircraft for the S.20 floatplane, G-ADHJ Mercury. The combination is seen on the River Tay at Dundee. Mercury separated from Maia over Dundee to fly 9728 km (6045 miles) to Alexander Bay in South Africa, a record distance for a seaplane.
