Flying Boat Moored on Thames. Moored at Tower Pier with the Tower of London in the background. The London Thames carried a different boat yesterday this 35-ton Short Solent, largest of Britain's commercial flying boats. The Solent, first flying boat to land in the London area for twenty-one years, touched down at Limehouse Reach and taxied up the river through the Tower Bridge. The bridge was raised to make sure the Solent's high tall did not foul it. She was finally moored near Tower Bridge. Ma
