BDP's team was among those jumping off the nearly complete Wing Tower in Glasgow last week. The charity event was presumably not the use for which Richard Horden had originally intended the tower, now part of BDP's Glasgow Science Centre. But it is probably the last time when queues to go up the building will be less than an hour long. It is estimated that a visit to the top of the world's first rotating tower is likely to last half an hour, and once it opens in the spring it is likely to be as much of an attraction as the London Eye. But with only 20 people making each ascent, the scrum for tickets promises to be grim.
