This RSAF AH-64D has landed on the spot where Sebastian Vettel, Jenson Button, Fernando Alonso and Michael Schumacher all have raced their F1 cars during the Singapore Grand Prix. The attack helicopter is there to support the Singapore Army, which is having its open house at the heart of the city this weekend. Joining the Apache is a RSAF Super Puma helicopter, and these two are perhaps the first military helicopters ever on a F1 race track.
