# Is there some reason why ORBs don't land in a cylindrical cage? [duplicate]

Just watched Elon's video on How Not to Land an Orbital Rocket Booster (ORB), and I just look at that and wonder why they don't build a large metal cylindrical cage on the landing platform so if it falls the (padded) rim of the cage will keep it propped up. The cylindrical cage could even be telescopic and motorized, so there is no fear of accidentally tapping the rim in the landing process, then, once it's in the center, engage the motorized telescopic cylindrical cage to expand up to capture the ORB safely.

Another idea, inspired from the net idea here, would be instead of a net, just two clotheslines,

----- ----- <--- wires
|   | |   |
|   | |   | <--- poles
|   | |   |,


on either side of the landing area, and then when the rocket's in the landing area, clasp the two wires around the circumference of the rocket.

• The tanks are really thin and I doubt they would survive falling over and landing on a rim. Sep 14 '17 at 19:22
• @OrganicMarble, ok, so I'm just going to keep my question up as a statistic to add to the consensus that it's stupid to not have something like this.

• @JoshKing, exactly! I didn't even know these questions were already asked here. Is it somehow financially beneficial that some of them blow up?

• @JoshKing, how do they not technically lose any money?

• @JoshKing, I thought the whole idea was to reuse it...
