When you’re a Jet: London-based masterplanner and environmental engineer Battle McCarthy is working with architect Kohn Pedersen Fox on plans for this stadium for American football team the New York Jets, which will be on Manhattan’s West Side, facing the Hudson River. The stadium will form part of a sport complex called the New York Sports and Convention Centre, planned as part of the city’s Olympic bid for 2012. It will seat 75,000 people and will have a retractable roof.
