Delta Airlines Hits UFO ..ok here we go
Seems A Delta 752 while on descent to Chicago struck something interesting.
Nose cone / radome...all safe
On today's early news feed from RT...
My apologies couldn't load the pic, 28 Oct.

Well, did they count the birds and one is missing? 
Certainly does not look like a bird strike, even less a drone strike. Despite the opinion of "Aviation commentator Peter Clark" (in the nzherald story), based on that picture I am willing to bet that this dome collapsed spontaneously.
No traces, no apparent impact point, paint missing only on the places where it is bent, no hail traces, almost exactly symmetric collapse... This happened all by itself, no reason to suspect the feathered colleagues.
Maybe they chose the budget "made from re-used plastic bottles" spare part provider for the plastic caps on their 757s

If the aircraft entered cloud or rain the remains of a bird is washed away.
Domes do not collapse " spontaneously" , ever!
Seagulls is my preferred pray, record is 10 in one go. Just after V1.
Moto; Better 10 on the wings then one in the engine!
Remarkably little left to clean up when checking for damage.
My money is on a small bird, five cents worth.

One of many examples is this old PPRuNe thread:
http://www.pprune.org/rumours-news/334094-jet-nose-cone-caves-mid-flight.html
Sounds like an old problem of structural collapse of B757 radomes.

If it was bird, if was IFR on GPS as it struck exactly on the middle ! Aerodynamics + initial examination of the damage would indeed suggest a radome collapse,rather than hitting something.
Shape of collapse practically identical to the cited earlier NW event. Investigation will reveal whether it was simple material failure, or perhaps the delayed effect of an earlier damage (a small bird may not leave any readily recognisable traces, especially in summer when radome also full of insect impacts, during the visual will appear ok, possibly for weeks or months until this happens).
Highest verified bird-strike was FL370 with a vulture over Africa (Ivory Coast I think). There have been unverified reports of birdstrikes even higher than that.

If evidence is washed away after a plane enters a cloud or rain why do big remains stay on airplanes for days, weeks, months, or years? Why does bird strike evidence stay on airplanes stay on for days? I doubt many airliners go days and days without flying through a cloud or rain.
Depends on how you define "remains"
Basically the big pieces wash or are blown off
What remain days later in some cases are goop streaks of dry blood and tissue in dead air zones. ultra-violet light reflects back as yellow-green. After a scrape and a filtration wash of what looks like a finger-nail scraping a puff of down feather may pop out and presto the bird species and maturity is confirmed. Works for other foreign material like, dirt or blue-ice as well.

My vote is with the 'expert' opinions of the passengers...
"Must've been a pretty big bird — a Pterodactyl maybe," Thunder forward Nick Collison said.

Perhaps someone in SEA is still mad about them leaving...

Psychophysiological entity
Is there any correlation between the aircraft descent and the collapse on these incidents?
I'm getting a gut feeling that there was a peaking of negative pressure in the nosecone relative to ambient.

Very good point. I suspect one would see a differential since the cave-in is to one side.
