RAF Typhoon jets have arrived at an air base in west London ahead of a major military exercise to test security for the Olympic Games.
It is the first time fighter aircraft have been stationed at RAF Northolt since the Second World War.
Military chiefs are warning people in south-east England they'll notice an increase in air activity, in particular this weekend.
London 2012 organisers are also testing security and ticketing with a series of events at the Olympic Park in Stratford.
We've also heard details about the opening ceremony for the London 2012 Paralympics.
It is to be called Enlightenment and will feature deaf and disabled artists, local children and circus performers.
A flypast by Aerobility, a charity that trains disabled people to become pilots, will open the event at the Olympic Stadium in August.
