If Boris Johnson intends to protest like Arthur Dent by lying down in front of the bulldozers (Heathrow expansion plan, 6 June) I am sure someone could lend him a dressing gown while the rest of us repair to the pub for three pints of bitter. And if his plan fails, Boris knows all about how to work an improbability drive.

• The obvious solution to the third runway at Heathrow problem is to bring back the flying boat. The Pool of London would make an ideal airport, with the Tower of London converted into the terminal. Tower Bridge would be sold to the Americans, who thought that that was what they were getting when they bought London Bridge, and this would be used to finance the scheme. The flood barrier could be used to control the depth of the Thames, if necessary. Walking distance into the City, too.
