Jet nose cone caves in mid-flight

From CNN:

Jet nose cone caves in mid-flight - CNN.com

Article does not mention type of aircaraft but I'm guessing Boeing 757?

Have seen it on a 757 without birdstrike a few years ago, moisture ingress due eroded paint and surface finish , caused it to go all mushy . One of the reasons for moisture content being checked on a hangar check on a regular basis on a lot of a/c types.

I actually saw very similar damage caused by (believe it or not) a lightning strike! I was doing a turnround inspection and there was an obliterated Radome. Initially I thought it was a birdstrike but the lack of blood and guts proved otherwise. It appeared that due to the position of the radar scanner (it was at 90 degs to the normal) the lightning bolt tracked straight through the radome and earthed at the scanner rather than along the diverter strips, taking the radome with it!. We needed a new radome and radar scanner.

I see CNN have changed the headline. The original seemed to indicate that the crew overcame their initial inclination to keep the plane in the air forever:

Northwest flight lands despite mid-air damage

We´we had similar damage on 757s, both due to birds and lightning. Aircraft landed ok, barely missing the usual schools, hospitals, seniors homes etc. on the way. It´s a big radome, and not very "pointy".

Saw a bird go through the radome, miss the weather rx and puncture the pressure bulkhead on a 733 once.....

Good job it was not the windscreen me thinks....

A Concorde Is Disfigured While Parked in Brooklyn

By PATRICK McGEEHAN
The supersonic passenger jet known as Alpha Delta retired unscathed in 2003 after nearly 30 years of speeding back and forth over the Atlantic Ocean. But in less than two years in Brooklyn, it already has had its pointy nose knocked off.

In a multicultural crash in the middle of the night, the jet, a Concorde that is owned by a British airline, was hit by a truck that was hauling equipment from a Jamaican music and soccer festival. The truck clipped the distinctive nose cone off the parked Anglo-French jet about 3 a.m. last Monday, prompting an impassioned uproar among the jet’s band of enthusiasts.

To many admirers, the tapered nose, which could be lowered up to 12.5 degrees to clear the pilots’ field of vision during the jet’s steeply angled takeoffs and landings, was what made the Concorde the Concorde. Within 20 hours of the accident, photos of the damaged plane appeared on the Internet, and Concorde lovers were deploring the level of care it had received during its postretirement odyssey in New York.

Birdstrike? really.... have a careful look at the close up. You will notice
3 very visible indentations relating to some physical object striking
the nose cone. We are definitely not being told the truth about this
incident. Had "the object" striken further up, the windshield could have
been shattered with the subsequent possible loss of the aircraft.

Did the bird on the steps do a turn in the cockpit?

Radomed

Actually had one of these. Dodging detween two building CB (Yes, I know better now, before you even start, 411A!), in clear air , they obviously decided a current path was there and connected via our F28 (F100 grandfather for the younger players).

Big Bang, flash, smell, some of it Ozone, usual scary strike stuff, Radar stops--`Antenna failure' message on new supersonic Colour Radar display. On arrival external OK except for pinhole damage but internal layers of the radome has popped in due to flash boiling of moisture in the laminations and physically obstructed the scanner's movement.

The one time I had severe damage to a radome was most unpleasant, not only for the Canadian Goose but for the vibration and handling of the A/C. Not to be underestimated

Sorry Vancouver about your Goose.

Granted I am not a pilot and generally visit this forums to learn about
real aviation from alleged professionals. Normally I don't comment on
matter outside my experience. However being a professional structural
engineer I know that whatever struck the cone of this aircraft was no
bird or lightning strike. Any structural engineer or anyone with experience
in impact assessment looking at the cone of this aircraft would readily
identify 3 specific points of impact which could only be made by a solid
rigid object. I supposse your total ignorance in these matters reflects
your useless reply.
