Snerk...
Obviously a lot of the 'kids' today commenting on the latest SpaceX launch DO NOT remember or have not bothered to look at the history of the US space program...
The SpaceX team has shortened the build/test/shoot sequence an amazing amount, and continue to push the development envelope with every test. This time, they confirmed the 'issues' projected by modeling high angle booster return (didn't work), and found more issues with leaks on the payload package.
In the old days, this would probably have been one test a year...
