Beachgoers knew something was wrong when they heard a loud boom ring out as a paraglider spun out of control, killing its only occupant, extreme athlete Felix Baumgartner.

Mihaela Radulescu Schwartzenberg has paid tribute to her daredevil husband after he tragically died during a freak paragliding accident.

Baumgartner is most well-known for breaking the sound barrier with his body during a freefall from the stratosphere in 2012.
