Maybe the aircraft is on the bottom of the Indian ocean, but not totally flooded. It might move around with the current, so the pings would be picked up in different locations, but the aircraft would have moved by the time the ROV went down.
Imagine you were living with circa 1800 AD technology, and were looking for evidence of another civilization with circa 2014 technology. Keep in mind that this 200 year difference is nothing compared to the difference between modern technology and the technology of a race capable of building a Dyson sphere.
The existence of the advanced civilisation would be obvious to us because they'd be in our villages raping our women. So maybe aliens wouldn't be doing precisely that, but if they are anything like us they would be curious and hungry for resources. I think the it is significant that the only debris found on the lunar surface was put there by humans. Any sort of exploration of our solar system would have left debris, garbage, broken vehicles, etc. And if somebody invested in a Dyson sphere only 7 light years away, they would be keeping an eye on us for sure.
I doubt it because we would be deluged with holidaying spherians every long weekend. Earth beaches are the best. Also the construction process would have generated a lot of debris. Seriously, it is too close not to be noticed as such. If they were humans there would be trillions of them in there. Even if it was a ringworld sort of thing with a collapsed civilisation, there would be ships coming past and making radio noise, exhaust, etc.
it may have formed around a star like a planet does, then got ejected by gravitational interactions with other planets.
But if Jupiter interacts with anything, Jupiter isn't going to get ejected. The remaining object must have been a sizeable star. This star must be warm deeper down. I wonder if it is a good place for life.
One morning on my road bike, cycling on a suburban road. Tram tracks to my right, parked cars to my left, going about 50km/h. This woman was hanging out on the road ahead of me, Not really paying attention. I got to within about three metres and I swear I heard her inhale as she saw me in her peripheral vision and jumped back out of my path.
Because the discussion is about colonising the galaxy. Maybe the reason we haven't seen any other civilisations is that they reach a point where they are comfortable and see no reason to expand beyond their home planet.
But also the path from African human populations to space flight relied on many chance events. The geography had to be just right. Migration had to be easy enough to be possible for stone age people, but hard enough to provide a break from the old ways. The US finally made it to the moon, but that was after two distinct migrations: Africa to Europe and Europe to America. Along the way there had to be enough energy to keep humans from freezing to death in the north, but enough free time to do R&D, for hundreds of years running. The second world war could have wiped us out, because we finished it off with fission bombs, but then stopped using them, but without that experience and the cold war, the Apollo program wouldn't have happened.
Most of our energy right now comes from old stores of energy which we have been extremely lucky to find, and which will either run out, or become too dangerous to use due to resource exhaustion.
Our behaviour can not cope without scarcity. Look at Australian aboriginal people. Placed in an environment with relatively low scarcity, their culture collapsed. In the next hundred years automation will push large parts of our populations out of work. There will still be food and shelter for them, but will those people cope psychologically?
Personally I think there is a good chance that a workable population will get off Earth before things get really bad. Maybe 20%. Ask Elon Musk. I reckon he will drive the diaspora.
Yeah but the problem with human drivers/pilots is that they send SMS messages, update facebook, phone their girlfriends or go crazy and decide to kill their passengers. The engineers who build the vehicles do all those things too, but in an environment where their work can be checked and peer reviewed.
The best mass transit system I have seen is in Kuala Lumpur. It has no drivers. It is faster and more reliable than any other system I have seen.
Flying back they have to cancel momentum twice, and fly the reverse of the outgoing trajectory. And they have to fly their rocket towards land, which means that populations on the ground would be at risk.
Oil rigs are very expensive to move and maintain. It would be hard to achieve ROI doing it that way. They might be better off with an adapted freighter. They could get a ship for 10 million USD.
Having said that, many recent aircraft failures have been caused by the crew and I think fully automatic airliners should be looked at. Or at least keep a hostie around to blow the thing up.
I don't want to hit the main ubuntu server for updates. Maybe the push sync to the au server is broken. Hopefully somebody will look at it before tuesday.

Your demands are too high.
Its the 21st century. Lets try some re-engineering.

Yeah but that's Somebody Else's Problem.

I want a pedal/electric street legal hybrid motorcycle which I can drive on the freeway to work.

It might have a hub mounted electric motor. Some motorised bicycles use those.
US Harley fans will suddenly find a common purpose with jap bike makers.
Does it come with a heads up display?
Did I just read a computer analogy in an article about cars?

None of them amounted to anything. Post scarcity societies go nowhere. They don't explore or invent things. Its a dead end.

I doubt there is a transit system in the world with manually operated doors.

It used to be trawlers...
The issue is NOT whether they they recovered the stage, but whether it landed at slow controlled speeds
Also whether it landed at the planned location to within a metre or so, given that the plan is to land on a barge.
