Not many people realise that similar cost bungles led to the Sydney Olympics 100m track being only 96m long! The builders forgot a network cable trunk passed under the end of the track, so the timing system couldn't be put 100m from the startline. To move the other end of the track would have resulted in 4 rows of premium seating being lost, so the track was 96m. All true, according to the documentary 'The Games'.

But seriously - the London bid forgot the IT budget, but clearly remembered the logo budget, much to our great horror.
