that'll polish out: especially the left wing, which seems to be sans engine and maybe a bit shorter......

According to ASN:

ASL Airlines Hungary flight QY7332 suffered a runway excursion accident after landing at Bergamo-Orio Al Serio Airport (BGY), Italy.
The aircraft, a Boeing 737-400 cargo plane, departed Paris-Charles de Gaulle Airport, France at 02:54 hours local time. The aircraft landed on runway 28 at Bergamo-Orio Al Serio Airport at 04:07 but failed to stop on the runway. It continued until coming to rest at the side of a highway.

The runway length starting at the runway 28 threshold is 9209 ft (2807m). Failing to stop at the end of the runway, the aircraft travelled 300 m across two roads, a parking lot and a highway lane before coming to rest with the nose across another highway lane.


Looks like a hell of a ride.

Used to fly into Bergamo at least every week. Due to the lack of an instrument approach on RWY 10 aircraft would regularly accept some pretty hefty tailwinds coupled with a wet runway on 28 instead of circling to 10. I personally witnessed a Ryanair 737 come dangerously close to an excursion under those conditions. I'm not suggesting that the crew were landing out of limits in this case or that weather/tailwinds has been a factor but that kind of incident (runway excursion) has been waiting to happen at Bergamo for a long time now.

METARs before and after the occurence shows wind from 260 and 340 therefore tailwind was not a factor here. Obviously (nearly) anything can happen in a TSRA...

Including a rapid shift in wind direction.

The landing time at 2.07 UTC was the worst moment imaginable with the core of a line of heavy thunderstorms OHD the AD (see radar)

There was also frequent lightning in the area, for details and timing click on the lightning icons.

A 737 over-run. Now there is something you don't see every day! (Maybe every OTHER day)

This doesn't look like a quick & easy job to remove the a/c. What has happened to the LLZ aerial? What is the status of the airport? I can imagine huge disruption to RYR's schedules and other operators including all the night freight flights. What is in fact going on?

fwd energy

This is certainly an original attempt to get parcels "on the road" quickly.


The A/C seems to have had still quite some fwd energy on exiting the paved RWY end, despite the deployed speedbrakes.


A quick ckeck on streetview shows it went through:
1. the localiser antenna;
2. the perimeter fence;
3. a steel railing/fence along the perimeter road;
4. a concrete low wall + fence on top btwn the perimeter road and the parking lot;
5. another fence btwn the parking and the northbound inroad;
6. a double safety railing btwn the inroad and the main northbound lanes;
7. a double concrete blocks separation holding an earthen wall of a few meters wide; and
8. a double safety railing btwn the main southbound lanes and the southbound exit.......

With the radar echo posted above it's safe to say there was at least 2-4 cm of water on the RWY, you flying people will know about the braking action then.

One wonders what ATC told the crew about runway conditions. The a/c would have been light, I assume. Parcels weighting less than pax + baggage. What landing flap & autobrake did they use? Did they use TR's on a night arrival - noise abate? Where was the touchdown point? What was the Metar? I suspect, being dark, the touchdown point might not be assessable by ATC. However, the crew can answer the other questions.

The Metar didn't call for it...

That's the last Metar before the event:

LIME 050150Z 26011G23KT 220V310 9999 VCTS FEW040CB BKN080 23/16 Q1010=

The one after the event looks unexciting:

LIME 050220Z 34011KT 9999 SHRA TS FEW015 SCT030CB BKN050 18/17 Q1011=

The difference in temperature shows the passage of the severe thunderstorm line in between of those, there was definitely at least a 30-40 KN gust which is not being shown since no SPECI message was issued. Only looking at the Metars one could have been inclined to give it a shot, but with the impressive fireworks in the sky maybe not and ATC could have seen this and should have told them to wait:

https://kachelmannwetter.com/ch/rege...805-0205z.html

The storm was registered by the stormtracker

https://kachelmannwetter.com/ch/stor...805-0205z.html

And the analysis says (if you click into the storm center) that it moves with 61KPH and gusts to 70 KPH are expected - there will be now way with a storm moving with 60+ KPH gusts would be slower than than - rather faster.

Rat5,

Your assumption that parcels and containers weigh less is not correct.

Very often, the B73F lands at or near MLW.
