Two guys in a squirrel suit base jump the Burj Khalifa in Dubai, a 828 meter high tower (Highest building in the world, eight times higher than the Dom Tower in Utrecht) The suit increases their surface thus their drag (air resistance). In this way they increase their air time and will be able to steer their way. The parachute is only opened until close to the ground. In normal speaking terms the jumpers experience a free fall. Not so in Physics language! A free fall for physicists is when you experience a friction-free (weightless) fall. Silly guys those physicists!
