Here is a link to a (no doubt pricey) "collision-proof" drone: <http://www.flyability.com/>. The cage likely reduces payload for other things, but it might at least work with a video camera for recon, even if it couldn't do any rigging. Another lightweight option would be to use a drone to simply drape a string over a suitable anchor (if one could be found) and use that to pull up a rope later. Something similar was done years ago using a helium balloon for Top of the Cross in Carlsbad.
