Strong wind sends two planes aloft

Illustration of a microburst The air moves in a downward motion until it hits ground level. It then spreads outward in all directions. The wind regime in a microburst is opposite to that of a tornado." srcset="http://i2.wp.com/media.boingboing.net/wp-content/uploads/2016/06/Microburstnasa.jpg?w=641 641w, http://i2.wp.com/media.boingboing.net/wp-content/uploads/2016/06/Microburstnasa.jpg?resize=300%2C232 300w, http://i2.wp.com/media.boingboing.net/wp-content/uploads/2016/06/Microburstnasa.jpg?resize=600%2C464 600w" sizes="(max-width: 641px) 100vw, 641px" />

According to Wikipedia, a microburst is a "small downdraft that moves in a way opposite of a tornado." This video shows a microburst causing two small glider planes to spontaneously take to the air, causing the fellows in the air traffic control tower to use naughty words. I wish I could find out more information about the incident.
