Triple Whiskey Double Foxtrot We’ve all read the stories of epic wave flights. Climbs to twenty, twenty five thousand feet or even higher. Oxygen. Cold. Wave windows. Frosted over canopies. Lenticular clouds. Rotors. Cracking gel coat and diamond badges. When there is a strong wind blowing against a ridge, the air is forced up to several times the height of the ridge. If the air is cool and stable, it falls back down to the surface, compresses, and bounces back up even higher. The cycle repeats itself downwind of the ridge, and each crest gets higher and higher. People travel hundreds of miles to glider destinations that boast high wave flights, but you can find wave at PGC.
