But again, is it poor design, or poor maintenance? Most structural/control failures are from poor maintenance, not design.

I'm curious as to the advantage of the lower winglet. I understand the upper winglet keeps the airflow on the lifting surface, making the entire wing vastly more effecient, but I'm not clear on what the lower one does.

and I've been binging a bit on aircraft videos of late (The ATC ones with subtitles are my current fetish), and I've seen that little parachute thingy on a few planes. Whats with that?
