'Ruuunnn!' Spectators flee as US ship launch sends huge wave crashing towards them
A crowd of spectators watching a ship launch in Florida, US, fled as the vessel sent a huge wave crashing towards them.
Footage from November 2015 shows the M/V Harvey sub-sea being launched sideways into the water in Panama City.
