SpaceX posted a really cool video of almost successful CRS-6 first stage landing, on “Just read the instructions” Probably due to some horizontal motion when touching down, the first rockets stage tipped over and explodes in a ball of fire. This could well be due to the strong wind, as can be seen on the photos, below the video.
Elon also published some really cool photos from this landing.
