Agree.
Somebody very early on in the thread sarcastically commented abut the early reporting of the accident and it ‘not being related to the earthquake’.
I think we’re going to find it has EVERYTHING to do with the earthquake and the human factors related to haste is getting the Coast Guard aircraft on its way. Would be interested to know what , if any, FPL STatuS was being attributed to the CG flight.
Won’t be surprised to find a miscommunication somewhere between the Ground controller, the Runway Controller and the Coast Guard pilot leading to an inadvertent line up clearance being wrongly perceived.

My ADS-B and Transponder are most certainly the same box. No separate boxes here.

In FAA advisory circular AC43-6D, "Altitude Reporting Equipment and Transponder System Maintenance and Inspection Practices", it is repeatedly referred to as an "ADS-B Transponder."

If you disagree with this use of terminology, I suggest that it would be more productive to direct your comments to Mr. Jackie Black, as he is the the current division manager of AFS-300, and has the authority to revise AC43-6D.

An aircraft stationary on a runway is hardly visible from the rear.

at night.
looking through a hud.

Because it could. Stable approach. Aircraft can stop 1/3rd of runway length. I see aeroplanes landing at my airport braking harder as they have landed long. Safe landing. Aircraft on the runway? Tail nav light, maybe a beacon. Maybe a strobe. No other lights.

This absolute tragedy should give impetus to mandating runway status lights installation around the World which are currently used at major airports in the USA and first developed after the terrible accident in LAX. A completely independent system with no human input using microwave sensors which turn on centreline lighting in the TDZ plus holding points illuminate lights RED if the runway is occupied. And whilst we are there reduce the intensity of the new LEDs. You cant see much because they're are so bright.
In this case, if it was a runway incursion, the centre line lights would have illuminated RED. Don't land.

The DHC-8 props may have added to the A350 damage by severing lines. Let's be grateful that the hydraulics to the brakes were still working and that the crew were not incapacitated. They could have ended up in the drink or hitting more aircraft or structures.

Correct. Half the spotters and puddle jumper pilots have never seen a commercial airliner approach to a major airport. Done jumpseat so see the work load. No idea on if the weather was crosswinds or lumpy. So many nobodies on this thread as usual.

True. 5 dead could have been nearly 400.

JAL Collision
 

I won't try to speculate the cause of this horrific collision, but one thing that is obvious was the amazing speed at which the A-350 was evacuated!
A testament to the training and professionalism of the JAL Flight Attendants. Yes, the same hard working miracle workers we disrespect and abuse, as of late.
Furthermore, it was the disciplined Japanese passengers who did not try to argue or grab their belongings, following the commands of their crew. I think this may have had an entirely different outcome had it happened in the West!

Incredible! There really is almost nothing left of the plane!

NHK are reporting that a source from the Transport ministry has confirmed the Dash 8 was ordered to hold short of the runway.

ITN news are so on the ball on News at Ten!

A captain will live with the death of his mates. Feel sorry for him. Maybe the first officer had a HF. Alas the Captain is commander. Just Culture rules..

Was genuinely pleased that lessons have been learned and it took a fair bit of time to really get hold improving survivability. Airframes can be replaced. People can't

Hope that we get an accident report.
Currently my main questions are:
How did the Dash-8 wind up in "postion and hold" on an active landing runway? There is a clearance involved which requires a positive reply from the plane to the TWR controller.
So how did this communication broke down and why did the TWR controller lost the situational awareness?

On FR24 there seems to be a Delta A330 holding near R34R threshold at the time the JAL aircraft was approaching to land. One must assume the Delta crew did not see the Dash 8 on the runway or they would surely have given a warning on the radio.

Nose Cone Damage
 

Pure speculation but given the damage to the nose cone, this wasn't from dragging along the ground, this was from impacting the Dash I would say, in which case I believe the Dash was on the runway and the A350 was perhaps still in the air (flare) and that the nose and left engine struck the Dash

I would have said exactly the opposite. They had time to evacuate 380 people even though the aircraft was on fire from the moment of collision, which damaged the underside allowing the flames to reach the cabin floor more quickly. Eventually it did go up but if you go on YouTube and look at aircraft fires on the ground, most progress much faster than this one in aircraft where the hulls are intact to begin with...
Only a guess but as it was allegedly an emergency flight to the earthquake zone, maybe the “mission” led to excessive urgency and possibly a misplaced sense of priority? As for the tower controller, if the aircraft on finals and the ones near the holding point didn’t spot the incursion, then the tower stood very little chance.

So true. Perhaps future safety briefings need to be a lot more blunt:

”In Tokyo, everyone left their bags and stuff behind … and everyone got out alive.”

Time to scrap the pc airline-corporate-speak.

A350 on the runway stands higher than a DHC-8. Last DHC-8 to attack another aircraft was at Aberdeen.
