The drone ship uses a satellite link to send footage back. The turbulence from the exhaust rocks it enough that it loses it's connection. It dies on pretty much every drone ship landing.
... and why am I not surprised... someone has made an entire video about this
https://www.youtube.com/watch?v=hH75bVG7HBoHere's a land-landing with pretty good footage.
https://youtu.be/SlgrxVuP5jk?t=1255 Ok I watched both and the 2nd one was pretty cool...
But it doesn't explain what we all saw today... Getting from cloud level to siting on the platform in about 10sec.
In the video you provided it took 2 1/2 min to land,
after the 1st time it re-fired the rocket to slow it down
And a full 40seconds to land after re-firing the rocket the 2nd & final time...
No matter how you look at it, that's a heck of a lot longer than today's 5-10sec signal lost message.
Now I wish I would have hit "record".
