Go to 'Countdown Net Audio'  and there to 38:15 (actually 38:29)

The video you linked is only 34:18 long...

Yeah, it looks like they got confirmation of booster destruction, but immediately after a "but don't say anything!!"

Guess more of "oh, signals is really lost" which while you can't tell is it a destruction, you can be sort of sure it most likely is. Just like when Columbia broke-up, they didn't immediately say any problem off when comms goes off, nor when telemetry blanks. Sort of a reverse is the last Ariane V launch, where the rocket performs nicely other than losing contact for, like, the whole insertion. Payload magically survive though.

The barge isn't manned or nearly watched when they're landing, right ? Or will the blooper from this launch be the most spectacular...

The BFR is by far my favourite PowerPoint presentation. Here is a sketch.

By the way, Flat Earthers loved the landing of the side boosters from FH too.

Let me guess: "It's a launch in reverse"?

By the way, if you watch the webcast again closely, you get a glimpse of the 1-3-1-0 landing burn, up close and personal. The two side engines only fire for 2, maybe 3 seconds tops.

Wow.   I hadn't realized that it was assembled and transported horizontally and then raised up at the pad like that.  Sergei P. Korolev is grinning somewhere.

Its cheaper on infrastructure, no need for an huge VAB you just need an hangar.
Rocket need to be a bit sturdier, 
Now BFR will be interesting as  its larger than N1, and more top heavy, however it looks like they will mate second and first stage on pad 
The N1 transporter an ejector was gigantic

someone put together 4 different landing angels and synced the audio .Careful with headset on loud!!!

Spoiler


 


 

 

Nope, nope and nope on those last two videos. 30 years of watching Sci-Fi has trained my brain to scream "it's not real, it's not real". It's gonna take another 30 years to get it to accept the change! :D

Apparently the highest mileage on a car is about 3 million miles, which means it'll take the Tesla about another week n flight to beat the record.

The Falcon Heavy carries roughly 340,000 gallons of fuel, so by the time this Tesla hits 3 million miles, it will still have only made 8 mpg. Kind of a shoddy fuel efficiency if you ask me.

Of course, its mpg is destined to increase at a pretty steady clip. It should break 100 mpg in a 3 months, and it's only up from there!

Such a pity. ;.;

An air strike did seem a bit much, What with all the navy/coast guard ships around who could do the same thing with a dozen rounds from Ma Deuce. 

Well THAT tells us nothing.

They might be doing other stuff while some pilots needed practice in bombing or staffing. 
Military has a bit of its own logic here, was involved in blowing up a lot of M-72 rocket propelled grenades who was too old and had to be discarded so you train with them. 
It was lots of dudes so they was well past useful life, we was to late for the shootout but we got to blow up stuff.

Exactly.  EM-2 will probably be cancled.  

EM-2 will not be cancelled. No way. Sunk cost fallacy, they'd never cancel with no manned flights. Not gonna happen.

Kewl pics.

Why is the nose cone charred though?

You'll notice that it actually returns with some significant angle of attack, hence the kerosene soot even on the nose (and the flow along the fuselage would bring some past the nose, anyway.

Kinda surprised that nobody's talking about the fact that those boosters reversed from 1,000 mph, back towards Canaveral.  And THEN had power left to land.  How can they possibly be so much more efficient than anything flown before? 

 

That's basically 2.5 full launches worth of fuel for each of them..

Um ... remember that a booster nearly empty of fuel is much, much lighter than when it started on the launch pad.

Like the other guys said. :D Grab MechJeb, KER or some other delta-v readout, and try it yourself in KSP. A nearly empty booster with no payload has a surprising amount left.

Don't forget that empty KSP tanks and KSP engines are way heavier than they should be. By the time the F9/FH boosters/FH core hits the boostback burn, they've lost so much mass that even a small burn produces a large change in velocity.

For perspective, one of my RP-0 boosters has a 2.5 ton payload capacity, and an Agena upper stage of maybe 8 tons tops.

The E-1 stage beneath it starts at 1.4 TWR... and hits 13 at MECO, delivering 6000 m/sec of delta V. By MECO, that first stage is basically a tin can with a giant engine on it.
