A bad week for aviation

[Freightdog]

This week has seen two serious aircraft accidents with significant, but what appears to me to be disproportionate loss of life.

Azerbaijan E190, crashed in Aktau, Kazakhstan after what is probably Surface-Air missile damage.
South Korea, B737-800 crash after runway overrun following some inconsistent reports of various damage.

What surprises me is the number of survivors from an aircraft with serious control issues (Sioux city has been quoted in comparison several times)

Azerbaijan airlines crash, Kazakhstan


Jeju airlines crash, Korea


I’m sure that there will be a number of irrelevant comments regarding the types involved.

Seeing the footage here is absolutely tragic, looks like a textbook pilot landing without landing gear and some fuckwit put a reinforced concrete wall at the end of the runway. I know you have to keep morons from accessing an air field, but surely there is a better way to give a plane enough runway/ground to make a landing like this non fatal. So sad.

Birds, concerning yeah.
But Russia shooting 2 civilian aircrafts in 10 years, worries me more.

South Korea, B737-800 crash after runway overrun following some inconsistent reports of various damage.

Looking at this crash, it looks to me that along with the landing gear, the slats and flaps weren't able to be extended. Explaining a higher-than-normal landing speed and resultant overrun. Possibly due to electro/mechanical issues and or hydraulic.

What do you think @Freightdog

do you see slats and flaps extended?

The conspiracy nuts are out in force as usual.

I don’t see much of anything to suggest that this was configured for a landing.

A little understood part of aircraft design (from the POV of the layman) is the level of redundancy built into systems; the back up systems, and the known performance of an aircraft type.

The gear can be dropped manually in an emergency, flaps can be extended,
We can take off while having a catastrophic failure of an engine. Of course, we won’t be continuing the climb up to cruise altitude, but we can climb to safe altitudes, sort out the problems, and land back on one engine. Including do a go-around.
We need less than 2000m runway to land single engine, at maximum takeoff mass.
The chances of having lost all of this capability in one flight is incredibly remote.

For all of the negative hype, the 737 is a robust and capable piece of kit, despite the fundamental design age.

Comparing these two events, the least survivable I might have suggested would be the Azerbaijani. But as ever, very little is openly known about what they were dealing with.

I’ve not heard the conspiracy ideas, yet. Though it doesn’t surprise me. Do tell.
I heard a journalist try to get an actual expert to start commenting on irrelevancies, but he gently shut her down.

Do the different colours - green, yellow and white - represent altitude? If so, it was a roller-coaster approach, as the videos suggest.

Yes, https://www.flightradar24.com/data/flig ... 3#3879c26d

They do, each represents another altitude range. White is extremely low.

there's another graph with the vertical speed as well, can;t find it within seconds, but it was a roller coaster from the moment it was hit while it was in its' initial descent.
