Another early ejection seat was used on the Saab J21 push prop, the first was made on 1 June 1945. The first real use was on July 29 1946. A version using compressed air was tested in 1941. A gunpowder ejection seat was developed by Bofors tested in 1943. The first test in the air was on a Saab B17 on 27 February 1944.

Sukhoi 31M is equipped with ejection seat Zvezda SKS-94 for several years already. So far it is the only civil aircraft with factory-installed ejection seat. Can somebody add information about SKS-94? Here is more info about the seat —Preceding unsigned comment added by 84.239.158.86 (talk) 22:08, 8 July 2008 (UTC)
The article mentions leg straps that pull the legs towards the chair as if they are something unique to the F-104. That is simply not true. --J-Star 15:52, 2004 Nov 15 (UTC)
The utmost in contemporary ejection seat technology is incorporated in the K-36 series designed by the Russian Zvezda bureau.
At best this section is NPOV. But does this thing even work like this section claims? The whole thing should probably be removed if there's no source. Twinxor t 02:06, 17 December 2005 (UTC)
Until you have the courtesy to sign your contributions to the discussion, you will have little credibility. You come across as nationalistically partisan in agenda.--Buckboard 08:34, 2 December 2006 (UTC)
Please note that Vmin 150kph ejection limit on MiG-29's takes roots in the canopy being teared off by airflow in process of ejection, not in seat limitations. There was at least one successful 0-0 ejection from Su-24. —Preceding unsigned comment added by 217.174.97.107 (talk) 16:56, 10 March 2009 (UTC)
What's the meaning of "zero-zero" in zero-zero ejector seat?
While serving in VF-154 onboard the USS Independence (CV-62) in 1997 one of our F-14B Tomcats nose gear was blown off the oil slick flight deck and into the catwalk by another jet's blast. Fearing the A/C was going to fall completely overboard the pilots initiated a zero-zero ejection. Both pilots shot out, parachuted down into the ocean and were picked up by an SH-60F Sea Hawk without injury. The aircraft did not fall overboard but was out of service for months while the ejection seat/canopy system was rebuilt. Swaflyer 15:51, 11 January 2007 (UTC)
The "Zero/Zero" capability of ejection seats came to be in 1961 with the incorporation of a rocket motor on the bottom of the seat. The added thrust provided by the rocket motor propelled the seat high enough for safe parachure deployment. --Soon Bok 22:54, 17 October 2007 (UTC)
Came here looking for more information about the ACES II seat used in the F-16. A little disappointed I didn't find much. Only a picture. Hope you will at least link to a more detailed page on this.
The article Martin-Baker states;
Martin-Baker started to investigate ejection seats from 1934 onward, several years before Germany (1938) and Sweden.
Is this a date of invention? Or should the article be reworded to "the first working ejection seat was produced in Germany in 1938", or something similar. Emoscopes Talk 09:06, 17 January 2007 (UTC)
Don't bother. A patent for the ejection seat was already issued in 1930 (with first experience in 1929), see Anastase Dragomir. --Alex:Dan 00:14, 21 April 2007 (UTC)
Supersonic aircraft were not the driving force for ejector seats, were they? How many pilots were able to manually escape from fighter aircraft in WWII? (That would be a great stat for the article if anyone can look it up regardless.) Rather than supersonic speeds, I thought the driving force was merely the improvement of the technology. Tempshill 22:20, 27 June 2007 (UTC)
Can anyone please supply a reference for the bungee assisted escape of 1910? Thank you. Nick1961 (talk) 11:40, 1 June 2008 (UTC)
The article states that, "Some models of the F-104 were equipped with upward-ejecting seats, which led to several fatal accidents when pilots trained on the downward-firing seats rolled inverted at low altitude and ejected."
I've heard this claim, I've searched for instances of it happening, but I have never seen it verified. I've added a 'citation needed' tag. Rpstrong (talk) 18:23, 29 September 2008 (UTC)
This is an awesome article about the historical designs of both pre and post coldwar era aircrew ejection systems. However it is a common misconception that a seat merely leaves the aircraft when the handle is pulled and this is what I wish to clarify for some.
The ACES II ejection seat is catapulted out of the aircraft by a 2-stage rocket assembly lovingly referred to as the "Rocket Catapult". Upon exiting the aircraft the systems enviromental sensing unit takes in static and dynamic pressures allowing for one of the three modes of ejection to be determined. This information is in turn sent to the seats sequencing unit which in turn sends a signal out to the internally loaded munitions which both correct the trajectory of the pilots seat and allow for pilot - seat disconnection.
Upon ejection a "drag" chute is released to allow for the seat to reach the proper airspeed determined safe by the sequencing unit. It is only as this point that the actual pilot chute is released not before.
Again this is a brilliant article and I personally enjoyed reading it great job. —Preceding unsigned comment added by Sephios (talk • contribs) 01:46, 21 October 2009 (UTC)
No mention is made about pilots who, after ejecting, report a permanent loss of height of about 1" due to spinal compression. Chris Stricklin (sp?) of the F-16 airshow crash is a good example. Also, nothing is mentioned about pilots that are permanently grounded after an ejection. Not sure if its just the Americans who do this. 68.144.38.146 (talk) 02:24, 22 March 2010 (UTC)

--THE FOUNDERS INTENT PRAISE 01:16, 4 January 2012 (UTC)
Pilots generally lose on average one inch in total height due to spinal compression after an Ejection. Pilots are generally not grounded because of a single ejection, however after three total ejections a pilot is grounded but not removed from service. In regards to pilot safety the fact that the seat is designed for maximum survivability and not comfort is a testament to how many pilots have been brought back because it worked without a malfunction. Chris Stricklin unfortunately is not a good example to use since his faulty and wreckless piloting brough down his aircraft and endangered the lives of spectators and that of his ground crew alike. —Preceding unsigned comment added by 132.9.127.6 (talk) 00:40, 15 April 2010 (UTC)
I find it strange that throughout the development of ejection seats, I can't find any mention of improvements to the seat harnesses. All designs strap the pilots IN and DOWN, not one that holds the pilot UP. Imagine a suitably designed powered harness that also goes under the pilot's armpits to lift him UP off his butt at the moment of ejection charges firing, spinal compression injuries will be reduced, if not eliminated. At worst, dislocated shoulder joints are less harmful than a wrecked spinal column!Life is short, but the years are long! (talk) 05:08, 22 October 2011 (UTC)
You may be correct, but what I was thinking is similar to pre-tensioned seatbelts in case of a crash. the harness only have to tighten and lift him up half an inch at most to offload and share the loads with the spine. There would be three load points instead of just the pilot's seat. Broken arm and collar bones are much easier to treat than damaged spine.Life is short, but the years are long!

Having a system with a high likelihood of disabling combat aircrew who has to control his descent and potentially evade hostile forces may be considered to be very low on the list of design priorities. Ejection seats give crews in otherwise unsurviveable situations a chance to fight again86.154.37.250 (talk) 10:32, 3 January 2012 (UTC) Oops forgot to log inKitbag (talk) 10:33, 3 January 2012 (UTC)
There's an interesting 1981 Flight International article on ejection seats here; [4] —Preceding unsigned comment added by 86.112.68.219 (talk) 17:57, 12 April 2011 (UTC)
These don't make any sense at all. How come 0-Deg Pitch, 60-Deg Roll requires 0ft altitude whereas 0-Deg Pitch, 0-Deg Roll requires 116 feet? How can this be more? Furthermore, if a "light-weight crewman would reach an apogee of close to 200 feet if they ejected at ground level with zero airspeed" how can it only require 150 feet altitude to eject from inverted? Something doesn't seem right... Turkeyphant 22:10, 17 July 2014 (UTC)
I seem to remember reading about an aircraft that was designed to blow the tail free when the ejection system fired, to ensure the pilot didn't get clipped by it on the way up. However, I don't seem to see it in the article, and I'm %$^&*( if I can remember where else I might have seen it. Or did I hallucinate it?
*Septegram*Talk*Contributions* 03:01, 10 March 2015 (UTC)
You may be thinking of the several aircraft that had pusher propellers--Saab J21 and Dornier 335, as I remember, but I could well be wrong--with explosive devices intended to blow the props off.173.62.11.254 (talk) 19:02, 15 October 2015 (UTC)

I don't see such things as: How high does zero-zero ejection seat travel, for how long are the 12-14g's applied, etc. 2600:1700:4CA1:3C80:4D91:A5B2:7047:B1CE (talk) 03:48, 17 March 2018 (UTC)
The article states that "No real life land vehicle has ever been fitted with an ejection seat." MythBusters built a successful ejection seat, which passengers did not detect when sitting in the car. Parkerea (talk) 14:40, 7 October 2021 (UTC)
My father Chris T. Koochembere designed the ejection seat along with the catapult seat obsorbtion seat and the face shield that you pulled down over your face. He was mentioned in a biography named escape I have the original catapult prototype along with a picture , one of many of him kneeling down at the right side of the ejection seat with the catapult mounted on the wall behind him. 174.252.131.42 (talk) 19:49, 4 July 2022 (UTC)
