This is just a question I wanted to throw on here for any Learjet folks.

I'm just a dumb airline guy that was curious about Learjet drag-chute kits. The other day I was thumbing through a publication that advertises aircraft and noticed that numerous Lears had these kits installed. I actually thought it was sort of interesting. I've never actually seen them in use anywhere, is it typically an emergency-only device? Or was it due to brake-design on the 20-series, etc? Just curious...
