This is weird. I cannot think of any real danger to aircraft by the decay of small fragments of USA 193 debris. Most will burn up well above the flight altitude of aircraft. Those that don't, will be rare and not a real concern in my humble opinion. Moreover, hadn't "they" told us the danger was gone after they successfully shot it to bits?
The Public Relations behind this whole operation is bizarre, from start to end. I am at a loss to understand what is going on behind the scenes here. It is becoming a soap story.
Reading the NOTAM carefully, it seems actually to be more about trying to get information about where something might have come down, then that it really concerns the "danger" to aircraft. The latter merely appears to be the "vehicle", just as the hydrazine "danger" was in the argument to shoot USA 193. Perhaps some component wasn't that destroyed after all and they are after it. And no, that will not be the hydrazine tank.
UPDATE: Strike that last remark. One of the commenters to the topic on the Bad Astronomy blog here has managed to dig up the actual date of issue of this NOTAM. That appears to be Feb 20th, so before the ASAT strike. Which means it is clearly not the result of a debris-analysis made after the ASAT strike.
Still the issueing of this NOTAM remains weird. It does indicate that for some reason, they want to keep track of where debris comes down. Something among it has their interest.
Oh dear: that "they" sounds awfully conspiratory, isn't it? I apologize....and assure you I don't wear tinfoil hats... ;-)
