Is the balloon analogy still applicable? It has been so long since I first heard it half of the "understandable explanations" have since been pointed and laughed at.

Ah, the little grey cells are working. There is no fairing issue. All this Zuma fuss was a testing and dress rehearsal for the magic school bus (sized) payload on the inaugural Falcon Heavy launch. or maybe not.

@Vanamonde have you checked airtraffic24 for what was recorded at the time and location? Anything civilian owned that resembles a military jet should have their transponder on. US militaries also sometimes fly with transponders on, especially when they are transiting along busy routes. So there's a decent chance that this flight was caught in the receivers.

Perhaps you should have sent them proper soap too! Well, I did really read that bit wrong that way and thought to share my, ahem, amusing moment. Didn't intend to slight you or your story in any way.

This is what I read, and took me minutes to notice the correct wording, swear! Anything with nuts in it is definitely foul, too!

That's what I thought, but did not feel adequate to talk against quoted scientists without backup. Thanks!

Can you really negate the gyroscopic effect by placing an identical wheel that rotates in the other direction next to the original wheel? (Yes, I started wondering this reading the bicycle stability thing in the random facts thread.)

You need to read other threads in this forum too. https://forum.kerbalspaceprogram.com/index.php?/topic/157802-ksp-making-history/ https://forum.kerbalspaceprogram.com/index.php?/topic/158726-ksp-making-history-grand-discussion-thread/

Machete agrees with @TheSaint, see http://www.nomachetejuggling.com/2015/12/28/machete-order-update-and-faq/

To turn back towards the topic a little, have I got this right? In a nutshell gravity is that having mass sucks?

@shynung & @p1t1o, Where do you want me to drop this link? https://en.m.wikipedia.org/wiki/Wood_gas

Depends... whether them Dwellers find that amusing, that is.

Are those anti-pidgeon spikes attached on a strip to the grid fin?

What? Launchesnin 2hrs, posted 1hr ago? For once I have a chance to follow a launch live ... if this meeting ends in time.

You finally really did it. You fine folks! You set it up! Ah, thank you! Grand thank you all for HTTPS!! (what, I shouldn't post while extremely tired? Why?)

The board is very hush about them, but I found a pic anyway.

Well, I for one think that that is one seriously broken link.

Ethane has a vapor pressure around the same magnitude as N2O, if I read the internets properly. It is also the precursor to ethylene, which is widely used in plastics production, so it is commercially produced in large quantities. It's not as easy to come by as propane, but you might ask the same suppliers for relevant quantities of propane anyway...

Unless same unit flew both 1A and 1B (4 flights in total?)? Of course, [citation needed].

Wait, were the lasers supposed to be built on Earth? What does dumping that much power through the atmosphere years on end do to the local climate? At least I'm hoping the power isn't enough to have a significant effect on global climate but will accept any corrections.

Looks like @1stHorseman has started to trot. Wonder if he will be up to galloping when you introduce us to @5thHorseman.

I think this is one of the actually solvable problems in the scheme. "Just" fashion the sail into a center fed planar slot antenna and place the probe in the center. Sure you'll waste half your power transmitting in the wrong way and pick up some extra noise when receiving, but at least this layout leaves communication possible with both the preceding and succeeding probe. Now back to those unsolvable problems... how exactly does one condense a solar sail nanoprobe out of a puff of hot plasma?

None of the issues cited hinge on whether the vehicles have a driver or not. Human psychofysiology hasn't meaningfully changed in 70 years. Say, one in every street corner is not enough? And if you add signage to every potential destination within a 400 meter radius, you will have so much signs that they cause way more confusion than help. (~400 meters is the empirically measured catchment area for a bus or tram stop within which most people don't find the walk irritating.) I know it may seem shocking to people interested in technology, but majority of folks still prefer to navigate by their eyes. Many even find being forced to rely on devices cumbersome. Time of course will change this over a few generations, but no navigator will ever better seeing your destination and the route there. Where does this bus go? Do I care or am I just travelling for travelling's sake? Taxis of course work from anywhere to anywhere, but they share the disadvantage of private cars in that they only move few people at a time. All you save is the parking requirement. Get in or out, how? On your feet, by walking, of course. The streets in S-E Asia are still full of rikshas. Ownership or driverlessness does not change the fact that small transports just are terribly inefficient in the amount of real estate they require. Rikshas in S-E Asia also deliver you right to the door of the shop, house or other destination you are going to. That is not possible in a vertically separated architechture. We have that separation right now. Well, cargo tunnels also run pipes and wires where convenient, since the latter don't need constant attention and the former can deal with the rare blocks when they are needed. And carriages and pedestrians are horizontally separated rather than vertically, because that makes changing from one to the other so much more convenient. You personally may not mind the issues so much. But urban design has to serve the masses.

I think those sorts of announcements are strictly illegal under EU rules. Wonder how that meshes with their moving into the US a couple years back... That said, I feel sadness. I think the technical premise does have merit. It just needs to be executed with due engineering. And find a business niche of course.

Separating wheeled traffic from pedestrians was tried at least in my country in the 50's and 60's. Those neighbourhoods are consistently voted worst places to live, work or visit in. Unanimously by users of all transportation models too. The issues directly arise from the vertical separation: you arrive on the traffic level, be it by private car or public transport, but your destination is on the pedestrian level. So you cannot see the route from your parking spot or bus stop to the house or business you are looking for, you must first find a way to the other level. Only then you can seek out your actual destination. Same trouble going back, you must remember which stairs or lift you came up with or you may spend ages looking for your vehicle. Then you haven't completely separated pedestrians from vehicles, as people leaving or entering vehicles must still get close to them. In fact you never can completely achieve that separation simply because people are using those vehicles to get from A to B and by necessity must board a vehicle at A and disembark at B. Finally the lower levels tend to be dark, closed concrete worlds. Places like that often make people scared, even if only sometimes for a good reason. Having to daily go through scary places does not happy people make.
