In this specific explosion?
You understand that this test was too early, proved nothing and had little to no way to mitigate the likely explosion that they expected?
And that the impact on the nearby residents, the wildlife were not taken in consideration?
But it's fine because "surely they learned something"?
You should move next to the test site, I'm sure you'll be glad to be one of the people affected.
I'm sure this did not rush the launch. I'm sure people aren't going to get cancer because of a 420 bit.
