So far this morning, the only "strange noises on ISS" I have heard is static.
No DPC yet.

Also, much of the juicy information is sent to the crews via the various
"forms" such as form 24 and the daily tasks lists, at least on the USA side.
The russian conversations seem a bit more candid, but for them, there is no
sense of panic if they hear a noise.

I think that the USA is acting somewhat like a backseat driver. They see/hear
stuff, but they can't do anything because the russians are at the wheel, and
the russians aren't panicking, while the USA is affraid it might be
serious/catastrophic/dangerous (like any good backseat driver would).

What should be asked of the russians is whether such sounds had been heard on
MIR as well.
