Nobody ever, then or now, keeps a 'continuous track' on passive space objects, it's an absolute physical impossibility.
Once or twice a day you may get a pass through a radar fan and get an estimate, of varying accuracy depending on range and aspect angle. About as often, you may get a 'hit' as an object passed through the 'Fence' -- but without any usable speed or direction measurements.
The calculations required to correlate those 'hits' with a catalog of orbiting objects of different size and origin, was daunting in the early years. Most objects weren't transmitting, and nobody could read their license plates or even tell much about their shapes and sizes except by guessing based on brightness and radar signature.
Confusion over which object was what, was frequent and not unusual.

Yes. They may have known where the expended rocket casings (the second stages) were but the object was not a rocket casing. And it wasn't being tracked because it was mistakenly thought to have deorbited.

I just got a video file of the onboard STS-88 TV during the thermal cover escape sequence.
You can see copilot Rick Sturckow at the left window, Nancy Currie at the right window,
Sergey Krikalyov with the Hasselblad getting those detailed images we saw on page 1.
And there's a long sequence of the slowly-tumbling thermal cover, clearly the very same
object previously misidentified as the 'Black Knight' satellite. It's viewed through a dirty
window but the shape is unmistakably the same.
The file is about 4 meg, but I don't know how to upload it somewhere where we all
could play it and view it. If anybody wants to volunteer, U2U me and I'll real-email it
to them.
The video removes ALL doubt about the true identity of those bizarre-looking views,
so everybody really ought to have a chance to see it, if they can handle the truth.

Satellite
Refined radar analysis improved the size estimate of the object and more precisely calculated its orbit which showed that it was the recovery capsule from Discoverer 5.

Most fantastic of all is the February 24, 1960 Air Force order to its personnel to "treat sightings of unidentified flying objects as serious business directly related to the nation's defense." The order was issued by the Air Force inspector general. This, in the face of thirteen years of consistent denial by that same Air Force that there actually is such a thing as an unidentified flying object, specifically termed U.F.O., or "flying saucer."

Less.
But you are relying on the initial size estimates based on radar data for that 19 foot figure. After more radar observations it was determined that the object was about 3 feet in diameter and 2 feet long.
The actual statement in the New York times article was "nearly as big as the upper stage of a Discoverer rocket".edit on 6/4/2013 by Phage because: (no reason given)

Runaway trunion pin cover. Thanks Jim!
In this video you can hear the inside crew speculating on whether the spacewalkers would have a chance to grab it if it floated back.

Up to this point, as an experienced broadcast radio engineer including using communications satellites, I think the story seems to hold together. LDEs have been very occasionally reported (mostly between 3 and 30 MHz) since the 1920s. Although we have more sophisticated equipment to detect and measure them, the bands are much more crowed now and such echoes are more difficult to detect, particularly by casual observers.
How much penetration of the ionosphere do you get at 3MHz? It's not a really good band to do satellite communications with - the ionosphere's pretty reflective down there. Until you start getting up into the 10MHz area, you won't get much through the ionosphere, and even then it's pretty reflective/opaque most of the time, especially during the day.
I wouldn't think a satellite would be a likely source for LDEs in the 3-10MHz range, maybe 3-20MHz if you're getting daytime LDEs.
Anyway, now we have all wasted 18 pages of the internet discussing the subject, I found THIS from Skeptoid,com where Brian Dunning seems to have picked out all the 'facts' separated the different strands from muddled stories and has provided a very rational explanation why the whole Black Knight stuff is bunkum!

I've just got the actual STS-88 downlink video of the EVA-2 where the crew was installing thermal covers on Node trunnion pins, and one drifts away, and the crew comments on it ['about 30 feet out the commander's window'], and we'll try to make it available shortly. The video looks exactly like the still images posted by the OP.
I'd sure like to hear from anybody who has changed their minds about the possible identity of this 'bogie'.
