I'm very interested in the physics behind being able to move through the air without disturbing it. Are there any realistic theories how that can be done? I guess even unrealistic theories, but I'm looking for information from credible sources.
I have heard theories, but no one really knowns, otherwise, we would have already figured it out. What we do have, is proof that the objects exceeded the speed of sound and not produced any sonic booms. In fact, an object was tracked over the Washington D.C. area doing 7200 mph and no sonic boom noted.

Hypersonic UFOs
Barnes quickly checked the consoles; both scopes showed the strange blips. He called in radar technicians; they found no flaw in the set or antenna. Worried, though the low speeds didn't indicate Soviet bombers, he called the Washington Airport tower. To handle local traffic, the tower has a separate set, an A.S.R. (Airport Surveillance Radar) with a 30 mile range.
Tower operators Howard Cocklin and Joe Zacko both reported the strange blips on their scope, and in the same position. So did Air Force radar men at Andrews Air Force Base, which uses an A.S.R. set. Not only that, visual observers at both points could see mysterious lights moving in the sky.
Flashing word to Air Defense, Barnes turned back to the scope. The unknown visitors had separated, were now over Washington, two near the White House, one close to the Capitol.
A few minutes later, the controllers bending over the scope got a new jolt. One blip track showed an abrupt 90- degree turn, something no plane could do. As the sweep came around, another of the strange objects suddenly reversed, its new blip "blossoming" on top of the one it bad previously made. The unknown craft, or whatever it was, had stopped dead from over 100 m.p.h., then completely reversed direction - all in about five seconds.
"Then we noticed another strange thing," Barnes told me later. "Some blips suddenly disappeared, between sweeps. I couldn't explain, until Jim Ritchey called 'Casey' Pierman to check on one group of the things."
Captain Pierman, flying a Capital airliner, had just taken off from Washington. In a few moments he radioed back that he saw a bright light where the scope showed one of the objects. At the very instant he called the Center, the object raced off at terrific speed.
"It was almost as if whatever controlled it had heard us, or had seen Pierman head toward it," said Barnes. "He said it vanished from sight in three to five seconds. But here's the important point: at that very moment, the blip disappeared from the scope.
"That means it must have raced out of our beam between ten second sweeps. It could have done this in one of two ways: First, it could make a steep climb at terrific speed, so that in ten seconds it would be above the vertical area swept by our M.E.W. set. [The beam's average altitude, at its highest point, is from 35,000 to 40,000 feet, far out, but it is much less near the airport. At 30 miles, it is about 8,500 feet, sloping to 1,200 at three miles.] Second, it could race horizontally off our 34 mile scope within ten seconds."
Considering the objects' relative position, just before they vanished, this last would require a speed of from 5,000 to 7,000 m.p.h. At the time, this seemed unbelievable to Barnes and the other controllers. But Captain Pierman later confirmed the objects' tremendous speed.
"They'd go up and down at terrific speed, or streak off and disappear. Between Washington and Martinsburg, we saw six of these fast moving lights. [Control Center showed them at the same position.] I don't know what they were, but they weren't shooting stars."
Another confirmation of the visitors' incredible speed came later that night, from the Washington tower. Operator Joe Zacko had been watching the A.S.R. scope when one of the mystery objects abruptly appeared just west of Andrews Field. Unlike the slower M.E.W., the A.S.R., with its 28-r.p.m. antenna, can track extremely high speeds. As Zacko watched, fascinated, the blips made a bright streak or trail, heading north- northeast toward Riverdale. Then the trail ended as swiftly as it had come.
Howard Cocklin, hastily called over by Zacko, also saw the bright trail. Together they figured the object's speed from its trace.
It had been making two miles per second -7,200 m.p.h.
"It was as if it had descended rapidly, almost vertically," Cocklin told me later. "That would bring it suddenly into the A.S.R. beam area. It seemed to level off for those few seconds, and then abruptly ascend out of the beam again."

I guess one problem I have with the alleged alien spacecraft theory is combining "magical" technology (no sonic booms, for instance) with mundane technology we already have (multi-colored lights). IMO, it stands to reason that if they have fanciful gadgets like anti-gravity,...
There are those who are working on the so-called "fanciful," and there were those who once tagged the idea of an airplane as fanciful.

NASA Anti-Gravity Experiment Due to Start
NASA's continuing interest in exotic propulsion will soon result in another test of the controversial
Podkletnov device which consists of a spinning superconducting disc that results in .5% to 2% weight reduction of anything placed above it.
