What is even more impressive is in those rare instances when a commercial aircraft does a forward slip to lose altitude fast. Don't see many of those. There was one time when I could pretty much see the runway ahead looking through the FC window. I bet the pilot who decides to do that is a current glider pilot.

Can't say I've ever been in a slip approach. I wish though! The most impressive approach has been a 50 kt direct crosswind while landing on SFO's 10R during last winter's torrential rains.
Talk about a crab angle!
Also, slips are my favorite thing to practice when doing touch and gos.
