He didn't invent it, but he's certainly popularised it. It's an old engineering term, especially in aerospace.

Latest Musk utterance:

"Landing video will be posted when we gain access to cameras on the droneship later today. Maybe hardest impact to date. Droneship still ok."

So it went a bit TITSUP then?

That too.

Just for interest, here's some footage from the other barge, "Just Read the Instructions", taken back in January.

Although it suffered some damage from the failed Falcon 9 landing back in January (the one where the leg collapsed), the damage shown here was caused by being smacked by big waves in the Pacific.

Quite difficult to work it out even with Musks explaination

It sounds like it ran out of fuel (or at least part of the fuel makeup)

Sounds like the combustion ran out of oxygen but it could be a pump or the nitrogen back pressure system (also used to drive some of the controls etc).

It looks like it was almost OK. Whatever went wrong must have gone wrong in the last few seconds. Did it actually fall over and/or explode?

From what I can glean from other sites, fuel depletion caused its last 20-50 feet of descent to occur rather faster than was optimal. The legs concertinaed, as indeed, sadly, did the engines, this resulted in a fireball, presumably from split fuel lines, and it caught fire. Still seems to be vertical, what's left of it.

Thanks. I couldn't see it topple over or any sort of explosion. They'll have to build in crumple zones smile

Well, they already did in the legs - just not big enough ones. Maybe they need to make the entire deck out of rubber like that bizarre aircraft carrier in the 50s ...

For missions which are going to be marginal on fuel, I wonder if adding a couple of small ( recoverable ) boosters to the first stage would help scratchchin

Here's an image stabilised version:

It appears that it actually landed near-upright, but ruptured itself and burnt up on the deck. So close are the margins between success and failure.

It looks like someone stubbing out a giant cigarette.

It actually DOES go over. It's much clearer in that stabilised image.

I wasn't sure, but you can maybe just make out it toppling from left to right. Could be white smoke though.

Really need the landing ships's view. They clearly delay this sort of thing to stop the 24-hr news cycle fixating on it..

Not to mention the on board footage. They did show a brief glimpse from the on board camera in the live broadcast.

Man, that was so close.

But that video really does give a perspective on the landing sequence, thing comes rocketing in [ouch] slows at the very last second to a hover manouvers into position and lands.

great footage .

The foreshortening effects of the distant camera makes it look like it's hovering, but the Falcon 9 can't actually do that.

The landing flotilla and what's left of the rocket are back in port now:

'That'll polish out'

Does it count as a RUD still?

Looks like SpaceX may be facing an unforseen price hike from the Port of Canaveral for bringing their boosters into port there. The Authority is considering creating a new category of cargo for 'aerospace items' which will be charged a higher tariff than SpaceX are currently paying.

Seems a good way to ps off a customer and force them to look elsewhere - like building their own dock on the lagoon right next to their assembly building at Pad 39A, using the navigable channel created for delivering Saturn V parts
