Apollo, Matt

When we put the north door on HAM4 last week, we noticed that first contact was still on the inside and outside of the viewports. This morning Apollo pulled the two viewports in question off the door (I did particle counts of the cleanroom and of the purge coming out of the chamber through the viewport aperture on the door and all counts zero).

The top gun was used in the removal of the first contact to blow during and after the first contact was peeled. The first contact must of been some of the original first contact and been on there a long time as it took quite a bit of force to "break the seal" to get the first contact to start to peel (it was a pour application of FC on the viewport it appeared).

After peeling I inspected the viewports. The one that came off the centre of the door looks like it has a scrath..and I want to say its on the inside, and its not in the centre but off to one side, perhaps 1-1.5inches long,  but I only had a quick look and pass it off to the experts to do a more detailed look as I didnt have any swabs, etc on me to investigate it. I shoudl of taken a picture. Didnt even think of that I am sorry. In the meantime I asked Apollo to put a blank on that port. The other viewport looked fine and so I informed Apollo to put that one back on in the same spot it came off.
