What?
Oh, and it wasn't Einstein who defined insanity...although he gets credit for it. He said he never said it.
Walter Hagen said it to Bobby Jones in the movie "Stroke of Genius". And that match was about 1925, so that statement's been around a while......LOL!
As has the condition, which I have been told bears a 'legal' definition, but no true medical condition, per se. Apparently whether one is competent or not is a matter of legal function, not whether they are free in sufficient degree from the spectrum of conditions that might interfere with that level of functionality.

As to the soup d'jour here, I believe Pearce's intent was to canvass the public such that a person with living recall might be found, as to the Earhart transmissions. A noble thought, but given that we just lost Betty Klenck Brown - a contemporary and possible (likely, some of us believe) witness, IMHO it seems the odds may be vanishing.
By Ric's comment, I take it that he shares my sentiment to some degree - that such a thing is unlikely to surface at this point in time; hence, repeating the exercise further would not increase the chances of success, at least as some of us see it; were one to feel strongly enough about that lack of prospect then the Hagen-Jones prospect seems to fit (could one rationally expect a different result than that already realized).
That said, I'd of not bet against Jones taking a second shot...
Mr. Pearce cuts to the obvious, if I interpret it correctly: if we knew no one remains alive who heard the broadcast, then indeed there's no rational way to expect a reply (and one presumably would not waste one's time and money with more ads). But we don't know that none are alive, do we? Some are - my dad was a child of 14 and is still with us at 91 (but does not recall having heard Earhart on the radio).
I, and perhaps Ric, seem merely to apply a different standard and expectation than Mr. Pearce: no doubt there are those who lived at the time, but the odds of them now coming forward to report having heard something seem dismally small, hence we might think it pure lunacy to run more ads, were I to state it harshly - which I don't mean.

But to return to topic... I wish we could lay our hands on THE radio (an
'above ground' artifact, were it known to exist) Betty used: it would firmly answer a few things, maybe.
An educated guess (or perhaps more than that, depending on your own interpretation) says it probably was a Zenith model 1000Z “Stratosphere.” "When shown a color photograph of a Zenith 1000Z that had been restored to new condition, Betty positively identified it as the model she had used."
Or, what Ric just said...
