Without even clicking that I knew it was gonna be ETH Zurich... They do pure magic. Pretty much nobody _else's_ quadcopters can survive a motor failure... (But it'll come, presumably. Amazing software is cheaper than redundant hardware, after all...)

Not to detract from how cool this work is but the preconditions for this to work are quite far-reaching. It is based on bridging the reality gap by having that gap approach zero - by removing error sources from the real world rather than model and account for them. Same goes for other ASL work.
