Yes, sure. Well, again, thanks to everyone for the great questions. So, here is the dilemma and this also may help answer the question why does it take so long to get something into Aerospace that’s new. When you look at traditional materials, things that come from a mill or come from a foundry, or come from a primary metal processing industry? The material is created at the mill, at the foundry. It arrives in Boeing or GE or Lockheed Martin shop, they machine it, they weld it, they assemble it, they put it together they ship it. Additive Manufacturing is totally different. I was just at a conference on the International Society of Air Breathing Engines in Phoenix. And it’s appearing as if the FAA is going to take the position that for Additive Manufacturing, the material is created in the printer, in the box. That’s a radical departure from traditional aerospace materials when you think about that, most of the time the materials created somewhere else that comes into your factory, you process it, you turned it into a park and you ship it. So, I think the industry is trying to wrap their head around that. Quite frankly the regulators are trying to understand that too. And so, I think at least in Aerospace that’s what you’re seeing, a little bit of uncertainty as to exactly what is the goal, how high is the bar and then what do I need to meet it. But at the end of the day, I think all of that is good for us because the direction things are going to be going in are more scrutiny, more inspection, more proof, more evidence that the process is under control, not less. So, at least as far as we’re concerned, this is a positive move. And certainly to ensure the safety of the flying public, we think it’s a positive move as well.
