Indeed, in my honest opinion such data is much more indicative of an atmospheric phenomena than it is of ET. While we have no way of even trying to understand the mind-set of ET at this point, I don't really see the point of such maneuvers. I have heard the argument that such are evasive maneuvers, but to me that is complete BS. If ET wanted to evade he/she/it would use the acceleration and speed that is obviously possible and just bugger off, leaving any pursuing aircraft far behind and find another good spot to hover (and mutilate cows and abduct people for obscure experiments or making crop circles - whatever makes their boat float). No need for a highly erratic trajectory or to "hit the deck" in order to evade. It is just self contradictory.

Please allow me to elaborate a bit on the above. To take an example, an F-16 use a pulse dobbler radar using a set of 6 (?) wavelengths in the ~1.5 to ~4cm range, which means that they have a fairly high resolution. To eliminate atmospheric clutter, a number of dobbler filters are used. The problem is that to design such one needs to have exact knowledge of what is to be eliminated. Which we to a very large extent have. But what if some rare, atmospheric phenomena existed that actually would behave just like an aircraft, motion and radar return, except having abilities beyond those capable by mankind? Well, that is something we cannot filter out, as then we would filter out valid radar returns as well.
Guess what, such actually do exist and while rare, have been rather extensively documented. I am, of course, refering to what is known as the Hessdalen phenomena. From
this report I will quote:

Sometimes the light phenomenon, which appears very often several tens of meters over the top of the hills, shows a jerky motion along very short
distances (d < 100 m), with an almost instantaneous movement from one point to another.
So it exhibits erratic trajectories.

QUOTE
The light phenomenon is often accompanied by a pulsating magnetic perturbation with a period of few Hz and by small and very-short-duration pulsating ‘‘spikes’’ in the HF radio ranges (Strand, 1985).
So it can emit magnetic pulses, which can certainly interfere with radar and communication systems (sounds familiar?).

QUOTE
The light phenomenon often shows strong radar tracks, including when it is optically faint or almost invisible. In some cases in which it is visible, it shows no radar track (Strand, 1985).
So it can definitely show up on radar.

The light phenomenon shows a photo-reactive capability when a laser beam is aimed at it, systematically doubling its pulsation rate (Strand, 1985, 2000).
And it reacts to external stimuli in the form of energy. It can also move very fast and show incredible rates of acceleration (bottom, page 22):
QUOTE
it is possible from the measured frequency to determine the velocity of the emitting source, which changes rapidly (i.e., within several seconds) by a factor of 10 from 10,000 Km/sec up to 100,000 Km/sec.
And now it gets really weird (page 19):
QUOTE
Approximately 5% of the sightings during the three EMBLA missions were characterized by light phenomena of
geometric or symmetric shape (see Fig.
10). Such shapes can form in two ways: a) the more standard light balls join together in a sort of geometrical arrangement, often triangular (see Fig. 5), which
tends to dissipate over a period of 5–30 seconds;

some very-low-brightness objects, often with translucent characteristics and of constant brightness, appear
suddenly low in the sky or very close to the trees showing intrinsically geometric shapes, mostly triangular or ellipsoidal (Teodorani et al., 2000; Teodorani et al.,
2001; Teodorani & Nobili, 2002).
Rectangular shapes have been recorded as well (see Figs. 5, 10): in this case radiant power was very high and the top of
the ID was saturated. The reason for these shapes is totally unknown.
Emphasis mine. Not only do such phenomena have erratic trajectorier, move fast, have high acceleration capabilities and react to external stimuli,
they can also be rectangular. Or have other geometric shapes. Sounds familiar?!
Thus such atmospheric phenomena actually exist and are known. It that what has been tracked by various radars? We don't know, but we can't rule it out. And in my honest opinion it is vastly more probable compared to ET blazing around. I just don't see how we can rule such out.
