#2Here's a list that includes all their landing attempts:

After their first successful drone-ship landing in April 2016, they had two failures of Falcon 9 in June 2016 and Dec 2018, two failures (of core only) on Falcon Heavy in Feb 2018 and June 2019, and 47 successful landing.

#3well it would become noteworthy that their failures make news simply because they had taken the concept of recovering the first stage to the point of people just assuming it was how rocket launches are meant to be.
I remember the first video of one successfully landing after launching and being wowed but when two landed together then it truly felt like science fiction had become reality

#4SpaceX has made landing so routine that now failed landings are news.

#5I believe they do a little horizontal kick just before landing when they validate things are look good. Potentially something wasn’t right and it just crashed into the ocean like 100 yards from the drone ship.. the good thing is that spaceX seems to learn from all of these issues and compensates, so will be interesting to here what happened.

#6I recall that the last landing had an unusually hard touchdown.

I believe it's 48 successful landings after the 1st as they kept mentioning today would be the 50th successful core to land. (Which counts each booster separately, including the FH side cores, but you must have been doing that too to get to 48 since the first)

I watched this live with a friend. We had previously watched a couple of failures, and were almost expecting that one to fail as well. We went out of our minds when the smoke cleared and the booster was upright.
It does feel annoying when rocket launches, which are enormously complex, go right and get no press, but surface in the news when they explode or fail in some way. By most standards, this launch was perfectly successful, but every time the first stages crash the press treats this like some kind of major failure.

I wonder if they're deliberate? Like if you're 100% you can land in "normal" circumstances, maybe try perturbing the parameters or input data a bit... to stress-test your algos, as if simulating wind, earthquake, different planet's gravity, different atmosphere, different rocket, engine failure...

Now that these are used to launch their own cargo (no not paid launches) I'm sure every loss hits them hard.
