F22,
size: somewhat big
color: mostly grey

Then... little goldmine in the article:

A helicopter spotted the wreckage at 10:15 a.m. but did not immediately land because of the threat of hazardous materials.
"It was being considered a haz-mat scene," Hayes said. "They had to get the right gear flown out there to the location so that the pararescuemen and the crash site recovery folks could safely get down there and do a search."

Let me guess... made in china... full of lead paint...

Any crash site can be considered a hazmat scene... there are large amounts of highly corrosive hydraulic fluid in large aircraft, and possibly it was using a special (and no doubt toxic) fuel additive to mitigate the formation of contrails... to say nothing of what a fire will do with all of the advanced composite materials the aircraft itself is made from.

The latter is also one of the safety concerns for another of Boeing's latest and greatest, the 787. What's the point of using all sorts of safe materials for the aircraft interiors to prevent the formation of toxic smoke in a post-crash fire, when the aicraft itself is made from CFRP.

So when reporting to the scene, to "inhale deeply" would not be sage advice, huh?

[Coligny]

You sort of wonder why they sent a chopper without the proper hazmat team already on board...

Sounds like the start of a bad Michael Crichton movie adaptation...

An accident investigator I happen to know told me he always develops a strange cough whenever he visits a fresh crash site. So no, it's probably not good for you.

I think they were referring to the team who first spotted the wreckage... bit of a waste to send a hazmat team along with every single chopper out looking for the thing I would think.

I'm sure that's a good piece of anecdotal evidence that the aftermath of any wreckage is probably not the healthiest place to be breathing.

It is, actually

Not to mention that the materials the plane is mount of are top secret.
