:thumbsup: keep em coming, nice to see some different perspectives of the launch and landings, these guys were a lot closer than the last video I saw. http://www.iceinspace.com.au/forum/showthread.php?t=164582

The news feeds all cut the sound out.

Does anybody have links to the stage 1 centre core booster crashing into the sea near the drone ship ?

Would also make a great spectacle !

Elon Musk mentioned in the post flight interview that they were not going to reuse the centre core anyway.

I guess he would have preferred a soft landing on the drone ship to give the mission a 100% success

That's awesome. :thumbsup: Unlike the flame thrower. :lol:

[RB]

Which flame thrower are you talking about?
The one he sold on ebay or the core that didn't make it?
:lol:

That is awesome, thanks for sharing Dean.

Can anyone explain why they cause a sonic boom?
In simple terms I understand, they aren't travelling at over or near the
speed of sound in that phase are they?

[deanm]

The boosters get slowed to transonic velocity (still >Mach 1) with the re-entry burn. That slows them sufficiently to minimise aerodynamic heating - but they're still supersonic, hence the 'booms'.

gotcha, thanks Dean,
I didn't realise until I watched that several times how fast they
are actually traveling!
