A plane carrying diver and Olympic medalist Tom Daley has had to make an emergency landing in Russia after "a technical issue".
Today's statement from the International Olympic Committee suggests all is not well with the preparations for the next summer games.
The Aquatic Centre wings are gone and the ugly duckling has finally turned into a swan.
- The site in Stratford is due to host five matches during the Rugby World Cup in 2015
- The stadium will be the permanent home of West Ham Football Club from 2016
- During construction Balfour Beatty expects to employ up to 400 people, and hire local people where possible
Balfour Beatty has won a contract worth £154 million to transform the Olympic Stadium in east London.
Last summer, Balfour was awarded the contract to convert the stadium roof and will now lead the remainder of the transformation work.
West Ham will not be able to block Leyton Orient agreeing a separate deal to rent the Olympic Stadium, the League One club's chairman has disclosed.
Barry Hearn said the news had emerged from a meeting he had had with the London Legacy Development Corporation (LLDC).
West Ham won the bid to be the anchor tenants but Hearn said the LLDC had confirmed the Premier League club could not block other companies or clubs agreeing deals to use the Olympic Stadium when it was not being used by the Hammers.
Hearn told Press Association Sport: ""I was not sure if West Ham were guaranteed to be the only football club using the stadium and the breakthrough news for me was that the answer is no, they are just a tenant".
Engineers have removed a second pair of lights from London's Olympic stadium. The 14 iconic triangle-shaped towers gave the stadium its distinctive appearance during the 2012 games. The remaining 10 lights will be taken down before the end of the year.
Before the floodlights are removed temporary cables are placed across the stadium to keep the towers stable. The lights are then taken down in pairs. Each pair of lighting towers is lifted and lowered to the ground using cranes with a 600 tonne lifting capacity.
Work to construct the new 45,000sq metres roof begins in the spring. It will be completed by spring 2015 when final preparations for the Rugby World Cup will take place including installing concessions, toilets, turnstiles and hospitality areas.
The first floodlights have been removed from London's Olympic Stadium as part of work to transform the site into a multi-use venue and the permanent home of West Ham United Football Club.

He said he was "deeply honoured" to have been chosen for the role.
It was part of the Olympic legacy to provide new affordable housing for east London. But no-one has moved into the flats that housed the London 2012 athletes, because of delays. So families have been left with nowhere to live and no explanation. Our Political Correspondent Simon Harris reports.
Triathlon Homes has issued a statement saying it eagerly awaits the handover of homes from the ODA which it expects any day now. And the first residents could move in within a couple of days.
