In-House is always better, it seems...
Congratulations to SpaceX and many thanks for all the hard work (and, I'm sure, many sleepless nights) to find the failure point.
On a side note, given SpaceX's penchant for keeping things in-house, what are the odds that strut-making will be either brought in-house or Elon will quietly buy a small metal-company in order to control the quality of the part, which was, after all, the reason for SpaceX bringing so many things in-house in the first place.
