It's stuff like this that makes alpha- and beta testing fun. Bugs that don't break the game completely, and which you know will be addressed before gold, but which add a level of unpredictability and entertainment value while they're around. If this game is as successful as we all hope then most who eventually play it will never have the joy of seeing these sorts of shenanigans, nor the dubious fun of chasing a canister of fish as it whizzes past a landing pad structure like Maverick buzzing the tower.
And to be fair to the guy in this video, although he wasted a lot more time than I would have done and nearly destroyed his ship on the cow-catcher, he survived and he didn't get in many players' way (maybe that Sidewinder, it was hard to tell from the angle). He may even have got a canister or two. He eventually stopped nosing around the canisters and docked, but whether this was to buy more stuff, effect repairs (his hull seemed OK but he may have jarred some systems) or sell p-cells on the black market (does Aulin even have a black market?) we may never know unless he identifies himself. I can't find reference to his Backer number anywhere so he's either not a forum user or is keeping his forum ID separate.
Fair play to him for having a go. So many goes! From the moment he first stopped in the cow-catcher for a look to the time he re-entered the port was a whisker under ten minutes. More patience and confidence than I would have had. It's certainly not something I would have attempted in an expensive Hauler. I've tried it a few times in starter Sidewinders when there's been nothing to lose. Lost a couple of ships but never managed to scoop a can.
