The problem with that statement is that there is no "ejection button" on any Martin Baker seat version, which were in all F4.
Lol, I'm glad you caught this. :) The last time I saw an "eject button" in real life was in my DVD player. Of course there's one in James Bond's Aston Martin, as well, circa the mid-60s, but...
In every USAF aircraft I ever flew which had an ejection system, it was either in the form of ejection handles (located at the end of either armrest and either one would work, but you'd better have your other arm in a safe place or you might loose it), or a trigger ring, also operable by one hand. I flew a couple other systems where one's "ejection system" was manual bailout via the nearest open hatch, but that's neither here nor there.

Ejection seats have been known to fail due to safety pin still installed, inproper strap in of the pilot, or simply finger trouble, pulling wrong handles due to regression in a state of high stress; for instance with drill memories for other types of seats.
Hence the failure of the ejection seat cannot normally be attributed to an external cause
Improper strap-in of the pilot may cause a malfunction in the overall safe operation of the ejection seat, but not a failure of the firing mechanism. So long as the safety pins are pulled, the seat will fire, whether the pilot is strapped in or not. Admittedly my experience in only with three different seats, but I recall several stories from life support describing how seats fired due to either improper life support procedures or operator procedures.
Ejection seat safety inspection was a critical part of our checklist. If the seat didn't check out, we didn't fly. All the seats I ever flew were highly reliable. The trigger mechanism fired a simply, highly-reliable pyrotechnic charge which rapid found its way through the system. There were several interlocks, but when the pins were removed, the interlocks were removed, as well. These interlocks included both safety interlocks to prevent inadvertent firing of the main seat ejection charge (equivalent to a stick of dynamite for the older seats or an even more powerful rocket motor for the newer ones), as well as physical interlocks to allow for the seat being allowed to be removed prior to the firing of the main charge.
From what I recall, it involved three cases:
1. The sequence could not be initiated without a rather decisive pull on the triggers/ring by the occupant.
2. The sequence first progressed until all of the physical pin locations had allowed the system to know that it was safe to fire.
3. The sequence then progressed until all of the physical interlocks locking the seat in place had been removed by the firing sequence.
4. The firing charge resulted in the seat's main ejection charge being ignited.
Seemingly complex? Yes. But remarkably simple. There were conflicting goals: 1) Never allow any malfunction of the seat to initiate an ejection, even if a bullet struck a critical node. 2) Never prevent the ejection sequence from taking place if the operator (occupant) pulled the handles/ring.
Obviously these two goals can, at times, be in conflict, so if that had ever happened, we had training out the, er, well, backside of our brains, for something called "manual bailout," which involved releasing a couple of clips hold us to the seat, allowing ourselves and our parachutes to race to the nearest open hole, and dive out in accordance with prescribed procedures. Not as safe or as assured as an ejection, but it's been used with decent results in years past.
How in the world do I know all of this? For the same reason I instantly recognized Andre's comment about "the problem with that statement is that there is no "ejection button" on any Martin Baker seat version, which were in all F4."
Been there, done that. Questions? I'm not going to supply unit information, so please don't ask.
But can we please stop all of this gross-ill-informed (what appears to me to be wild-*** speculation) regarding x, y, z, and the other thing but which actually has little (usually no) basis in reality?
Seriously, folks, if we're going to talk about UFOs, let's drop the ridiculously regenerated Internet crap and focus on something more substantial.
Personally, I don't believe they exist, for a variety of reasons, the least of which is, like insects, they'd either be everywhere, or if they couldn't exist, they'd be nowhere. Call it Mug's Razor, until we have a better term.
I do believe, however, they
could exist. I just don't think they would ever be so stupid as to allow themselves to be seen! If they ever did exist, I think they'd be totally behind the scenes.
Personally, I've yet to see any evidence whatsoever of any ET existence on Earth, save for a few bacteria which
may (by no means certain) have bounced back and forth to and from Mars in meteor impacts.
