yeah I feel like there is politispeak behind this one. the rocket performed well until it failed catastrophically 
With NASA it would be 'rocket exploded after launch' with elon musk you get some crazy shit. Whats with the people clapping when its spinning out of control too, bizarre! I just find it odd people are never that kind to NASA with... post launch analysis
Until I watched the video, even after trying to do 5 minutes of research, it was unclear to me if it exploded or not. Impressive PR
I don't have any real problem with rockets exploding, I know their complicated especially when you are trying to be cheap, but damn the initial presentation I got seemed like it was made by Elliot Carver (James Bond, Tomorrow Never Dies)! It seems that is cleared up now.
The "happy clappers" got to me, too----- they were apparently somewhere a long way from launch control.
Maybe they were all "gee'd up" beforehand to applaud on cue, like a "studio audience".
I prefer the "warts & all" approach of the old NASA launches, where there may be a lot of enthusiam upfront, but it is sensible enthusiasm, & dampened by a failure.
Here I will insert a story from 1960s Woomera rocket range when they were testing things like the "Black Knight" rocket, as a precursor to the "Blue Streak project.
It seems a particular rocket had 1/4 wave antennas protruding out of the sides to send signals to the "Acquisition Aids" sites at each end of the launch region, which in turn, pointed the RADAR in the right direction.
With the rocket vertical on its pad, the "Acq Aids" were tested, receiving equal signals at both sites from the antennas, which were at that point, horizontally polarised.
The rocket was launched, & all was well, until it turned substantially horizontal, & the "Acq Aids" sites lost the signal, due to cross polarisation signal level losses.
The near site reported a loss of signal, as did the far site, the computer said "Oops!" & the auto destruct operated---goodbye rocket.

"Interesting" thought the EEs, who mulled through the options of replacing the site antennas with circularly polarised ones, but
finally opted to take a rubber mallet & gently tap the rocket's antennas so they were at 45 degrees to its outside surface.
The signal was now reduced "a bit" in level for both vertical & horizontal attitudes, but there was no longer an around 20dB drop between the two.
