At the moment before encountering the Muan Murder Wall, there were 181 souls alive, healthy, and uninjured aboard Jeju Air Flight 2216.
At the moment after encountering the Muan Murder Wall, there were 2 souls alive, one severely injured, and 179 corpses, most mutilated beyond all recognition.
Multiple things had clearly gone wrong with the flight, and we're going to have to wait for results of investigations to determine what crew and/or ATC actions and decisions contributed. But the principle lethal mechanism was impact with the immovable object of the Muan Murder Wall, and the ensuing instantaneous deceleration, disintegration, and conflagration of the aircraft and the souls aboard.
Even with multiple contributing factors, had the Muan Murder Wall not existed at that location, the aircraft would have overrun the runway and quite possibly airport perimeter, but would have slowed far more gradually and likely encountered structures less substantial than the Muan Murder Wall.
Wikipedia has a category page listing 55 runway overruns: <https://en.wikipedia.org/wiki/Category:Airliner_accidents_and_incidents_involving_runway_overruns https://en.wikipedia.org/wiki/Category:Airliner_accidents_an...>
Sampling from that we find that such accidents often result in no or few fatalities, particularly on landing. E.g.:
- Sriwijaya Air Flight 062 (2008): 130 souls, 124 passengers, 6 crew, 1 fatality, 23 injuries, 130 survivors. The aircraft struck a house, 3 of the injured were occupants. The sole fatality occurred some time after the incident. <https://en.wikipedia.org/wiki/Sriwijaya_Air_Flight_062 https://en.wikipedia.org/wiki/Sriwijaya_Air_Flight_062>
- China Eastern Airlines Flight 5398 (1993): 80 souls, 71 passengers, 9 crew, 2 fatalities, 10 injuries, 78 survivors. The aircraft experienced a tailstrike during a go-around attempt in heavy rain / high winds, broke in three, and came to rest in a pond. <https://en.wikipedia.org/wiki/China_Eastern_Airlines_Flight_5398 https://en.wikipedia.org/wiki/China_Eastern_Airlines_Flight_...>
- Philippine Airlines Flight 137 (1998): 130 souls, 124 passengers, 6 crew, 0 fatalities, 44 injuries, 130 survivors. Ground casualties: 3 dead, 25 injured, as aircraft ploughed through a residential area. <https://en.wikipedia.org/wiki/Philippine_Airlines_Flight_137 https://en.wikipedia.org/wiki/Philippine_Airlines_Flight_137>
- American Airlines Flight 331 (2009): 154 souls, 148 passengers, 6 crew, 0 fatalities, 85 injuries, 154 survivors. Aircraft landed > 4,000 feet from the threshold with a tailwind in inclement weather. <https://en.wikipedia.org/wiki/American_Airlines_Flight_331 https://en.wikipedia.org/wiki/American_Airlines_Flight_331>
- TAM Airlines Flight 3054 (2007): 187 occupants, 181 passengers, 6 crew, 187 fatalities, 0 survivors. The exception in my (random) sample, this aircraft had a nonfunctional thrust reverser on the right engine. Lack of grooving on runway, heavy rain, hydroplaning, asymmetric thrust, and a large warehouse directly beyond the runway perimeter all contributed to the fatalities.
I've omitted one link I'd selected, Air France Flight 007 (1962) as that incident occurred on takeoff, not landing, where fuel load and flight profile greatly alter conditions and likely outcome, and isn't directly comparable. <https://en.wikipedia.org/wiki/Air_France_Flight_007 https://en.wikipedia.org/wiki/Air_France_Flight_007>.
If anyone cares to examine the 50 other listings on the Wikipedia category page, I suspect a similar patter of largely survivable overrun incidents prevails. The conspicuous lack of Muan Murder Walls seems significant.
- dredmorbius 2y agoI'm going through more of the Wikipedia category entries. AA 1420 (1999) is notable for similarities with Jeju 2216: The aircraft continued past the end of the runway, traveling another 800 feet (240 m; 270 yd), and striking a security fence and an ILS localizer array. The aircraft then collided with a structure built to support the approach lights for Runway 22L, which extended out into the Arkansas River. Such structures are usually frangible, designed to shear off on impact, but because the approach lights were located on the unstable river bank, they were firmly anchored. The collision with the sturdy structure crushed the airplane's nose, and destroyed the left side of the plane's fuselage, from the cockpit back to the first two rows of coach seating. The impact broke the aircraft apart into large sections, which came to a rest short of the river bank. Captain Buschmann and 8 of the plane's 139 passengers were immediately killed in the crash; another two passengers died in the hospital in the weeks that followed. 145 souls, 139 pax, 6 crew, 11 fatalities, 110 injured, 134 survivors. <https://en.wikipedia.org/wiki/American_Airlines_Flight_1420 https://en.wikipedia.org/wiki/American_Airlines_Flight_1420> Even though this aircraft also hit an ILS structure, fatalities were far lower than those of Jeju 2216, likely as AA 1420 had decelerated significantly both on the runway (despite severely limited wheel and air brakes) and its subsequent 240 cross-terrain slide. Atlantic Airways Flight 670 (2006) literally fell off a cliff. 4 fatalities of 16 souls. <https://en.wikipedia.org/wiki/Atlantic_Airways_Flight_670 https://en.wikipedia.org/wiki/Atlantic_Airways_Flight_670> Bangkok Airways Flight 266 (2009) literally struck a (presumably nonfrangible) control tower. 1 fatality, 71 souls. <https://en.wikipedia.org/wiki/Bangkok_Airways_Flight_266 https://en.wikipedia.org/wiki/Bangkok_Airways_Flight_266>
- yongjik 2y agoI looked up the AA 1420 crash report (linked from Wikipedia) and it says: https://www.ntsb.gov/investigations/AccidentReports/Reports/AAR0102.pdf https://www.ntsb.gov/investigations/AccidentReports/Reports/... > The calculated ground trajectory indicated that the flight 1420 airplane departed runway 4R at about 97 knots and impacted the runway 22L approach lighting system support structure at about 83 knots. 97 knots is 112 mph. Somewhere below another commenter said Jeju Air 2216 left the runway at about 160 knots (184 mph). It's a pretty big difference. I'm no expert, but my guess is that the main distinguishing factor of all the accidents where most/all survived is not the lack of killer berms, but the speed of the plane when it left the runway.
