This is quite a strange one. The observers disagree somewhat about the shape of these objects (one says they were somewhat figure-of-eight shaped or elliptical "pulled in at the waist", the other that they were diamond-shaped changing to elliptical), but otherwise the descriptions are pretty close. Basically these objects hovered for about 20 sec, an estimated 2 mi away, then rose perpendicularly at a rapid rate, then started to move horizontally to the right (generally East) through 62-65 deg (precision of "62" suggests an approximate angular measurement, presumably via azimuth circle attached to the mounted telescope, not a guess) in approximately 1 minute (horizontal motion duration = total duration 1.5 - 2 min, minus >20 sec initial hover and ascent, and minus un-timed final ascent to disappearance), all the while with this undulating or fluttering motion "like a magic carpet".
It's difficult to see any ordinary explanation other than windborn objects of some sort.
The wind is given as 4 mph from random directions, so may have been blowing fro W to E at the time. The angular rate is in the order 1 deg / sec. To achieve this angular rate at a windborne speed of 4 mph they would need to have been closer than about 340 ft. Since they were estimated to be 2 mi away this implies a distance error factor of about 30.
For objects estimated to be10-20ft across at 2 mi range the *implied* true or naked-eye angular size is = ~3 - 6 arcmin (effective angular size through the 6-power scope would be 18 - 36 arcmin). At say 300 ft range that angular size equates to about 6 inches, implying the same error factor for estimated size (6" x 30 = 15 ft)
Estimated speed(s) during the E - W phase or different poritons of it were 150 mph (Spot Intelligence Report), 200mph or 240 mph (witness interview reports). Applying the same error factor to the average estimated E-W speed would yield a speed of 6 1/2 mph, very close to the wind speed.
So IMO really it comes down to this question: Could the two observers - using the 6-power telescope - have grossly misjudged distance, size and speed all by the same factor of about 30?
If Yes, then these odd, shape-changing reddish things *could* in principle have been windborn objects a few inches across - given the rapid initial ascent, perhaps partially-buoyant deflating party balloons, or something similar. If No, then then we certainly have two of the strangest UFOs in the files.
