The Soyuz and Apollo flights launched within seven-and-a-half hours of each other on July 15, and docked on July 17. Three hours later, the two mission commanders, Stafford and Leonov, exchanged the first international handshake in space through the open hatch of the Soyuz. NASA had calculated that the historic handshake would have taken place over the British seaside resort of Bognor Regis, but a delay resulted in its occurrence being over the town of Metz in France.
