"The Political News Media Lost Its Mind"

The aerobatics skills of Russian pilots over the US destroyer Donald Cook in the Baltic Sea left the Pentagon and other US official running for cover in Washington over “aggressive close interactions” with Russian fighters jets.
Trends
Russia-NATO relations
Releasing the footage of Russian jet flybys in the vicinity of the destroyer, the US Navy said that its vessel has encountered multiple “aggressive flight maneuvers ...within close proximity of the ship,” some as close as 30 feet (10 meters) on Monday and Tuesday.

The set of incidents took place as the US ship, which had sailed from the Polish port of Gdynia, was conducting exercises with its NATO ally Poland in the Baltic Sea. The Navy announced that the SU-24 first flew over Donald Cook on Monday as US sailors were rehearsing “deck landing drills with an allied [Polish] military helicopter”. The numerous close-range, low altitude encounters were witnessed at 3:00pm local time, forcing the commander of the ship to suspend helicopter refueling on the deck until the Russian jets departed the area.

The next day, the Navy said, Russia caused concern among US sailors when a Russian KA-27 Helix helicopter flew seven times over the ship at low altitude in international waters at around 5:00pm. Some 40 minutes later, two Russian SU-24 jets allegedly made a further 11 “close-range and low altitude passes”.

“The Russian aircraft flew in a simulated attack profile and failed to respond to repeated safety advisories in both English and Russian. USS Donald Cook’s commanding officer deemed several of these maneuvers as unsafe and unprofessional,” the Navy said.

Judging by the videos released by the US Navy, the sailors were nonplussed by the Russian aerobatic skills. They gathered on the top deck of the destroyer to watch the Russian pilots.

“He is on the deck below the bridge lane...It looks like he’ll be coming in across the flight deck, coming in low, bridge wing level...Over the bow, right turn, over the bow...” the voiceover on the footage states in what looks more like an instructor’s advice on how to maneuver in open waters, rather than the panic that the central command presented it to be. At least on the video no one can be seen running for cover.

According to a US defense official who spoke with Defense News, sailors aboard the Donald Cook claimed that the Russian jets’ low altitude stirred waters and created wake underneath the ship. US personnel on the American vessels, also claimed that Su-24 was “wings clean,” meaning no armaments were present on the Russian jets that could have posed a threat to US operations in the Baltic.

Yet at the same time, the official noted, that this week's incidents are “more aggressive than anything we’ve seen in some time,” as the SU-24 appeared to be flying in a “simulated attack profile.”

The Russian overflights have caused panic over in Washington, with White House spokesman Josh Earnest calling the actions of the Russian pilots “provocative” and “inconsistent with professional norms of militaries.”

“I hear the Russians are up to their old tricks again in the EUCOM [US European Command] AOR [area of responsibility],” Operation Inherent Resolve spokesman Col. Steve Warren said during a briefing on Wednesday, adding that the US is “concerned with this behavior.”

“We have deep concerns about the unsafe and unprofessional Russian flight maneuvers. These actions have the potential to unnecessarily escalate tensions between countries, and could result in a miscalculation or accident that could cause serious injury or death,” the US European Command said in a statement.

In the meantime Adm. John Richardson, the chief of naval operations, thanked the US crew for keeping their cool during the stressful situation.

“Bravo Zulu to the crew of USS Donald Cook for their initiative and toughness in how they handled themselves during this incident,” the admiral said on Facebook.

Russia has yet to comment on the incidents but most likely the Russian air craft flew from the Kaliningrad region, bordering Poland. Kaliningrad is the headquarters of the Russian Baltic Fleet, which also includes the Chernyakhovsk, Donskoye, and Kaliningrad Chkalovsk air bases.

I had no idea the enemy had such amazing pilots who repeatedly can fly within 10 ft of boats in the water repeatedly.

The Most Costly Joke in History

transmorpher says...

Well there you go, even Wikipedia says dogfights haven't existed for some 25 years So the F-35 doesn't need to have maneuverability as it's primary design feature.

I think I see why we are disagreeing - we have differing definitions of dogfights, if you read the air battle encounters from the gulf war you'll see that it wasn't dogfighting in the traditional sense where planes are doing all sorts of fancy aerobatics to try to use guns on each other like WW1.
(And wikipedia has this defintion problem too because it seems to call all air engagements a dogfight).

It was all BFM at a fairly long ranges in the order of 10 miles. (which is considered close range, since a plane takes several miles to make a turn at high speed).

Not one guns kill in the air. A few close range missile kills, but mostly long range AIM7's. (well techinically it's called medium range, but it's it's still like 20-30miles).
There's a good reason why fighter planes carry one about 7 seconds worth of bullets, and only 2 close range missiles vs 6+ long range missiles.

https://en.wikipedia.org/wiki/Dogfight

Dogfighting first appeared during World War I, shortly after the invention of the airplane. Until at least 1992, it was a component in every major war, despite beliefs after World War II that increasingly greater speeds and longer range weapons would make dogfighting obsolete.

In the Gulf War of 1990–91, dogfighting once again proved its usefulness when the Coalition Air Force had to face off against the Iraqi Air Force, which at the time was the fifth largest in the world. Many dogfights occurred during the short conflict, often involving many planes. By the end of January, 1991, the term "furball" became a popular word to describe the hectic situation of many dogfights, occurring at the same time within the same relatively small airspace. Oh, fun fact, most of those planes 'dogfighting' in that 'relatively small airspace' were F15's...

But you can ignore that if you want. I mean, ACM schools that teach dogfighting even today probably don't exist...

Pilot ejects milliseconds before Mig 29 Crash

oritteropo says...

It was a similar story on July 24th 1993 at Fairford, when two MiG-29s of the Russian Air Force Russian Swifts aerobatic team collided in mid-air and crashed, but safely away from the public. Incredibly no one was injured on the ground and both MiG-29 pilots (Alexander Beschastonov and Sergey Tresvyatsk) ejected from their aircraft. Aircraft investigators highlighted that pilot error was to blame where it was shown on video that one pilot had carried out a reverse loop and flew into clouds, whereas the other pilot lost visual contact with his wingman and aborted the display performance.

Craziest Glider Low Pass Compilation

rich_magnet says...

1) Water is ballast. It makes them more efficient when gliding, but they dump it to lighten up for landing.
2) Gliders are tougher than they look. Look into glider aerobatics some time. They also need to have flexible wings as the wings are so long.
3) The one in the dirt is presumably an "out-landing" - one that didn't make it back and needed to land where it could. The spin? (Hopefully) aerobatics.

Steve, are you with me?

Incredible! Plane crash video from inside cockpit

aimpoint says...

I did a little amateur investigation, a bit of reading and some numbers but you can skip to the bottom for a summary.

The plane is a Stinson 108-3, 16500 foot service ceiling, 2400 pound gross weight limit (1300 empty weight), 50 gallon fuel capacity. Thats about 1100 of useful weight (2400-1300), with full fuel that lowers it to 800 (6lbs per gallon*50 gallons=300lbs), I saw 3 men in there the 4th passenger I'm gonna assume male, so lets say 180lbs for each (200 for the pilot) that comes to 740lbs for passenger weight. That leaves 60lbs for cargo. Although I couldn't see the cargo, they were still close to the weight limit but still could have been within normal limits.

The airport Bruce Meadows (U63) has a field elevation of 6370 feet. I couldnt find the airport temperature for that day but I did find nearby Stanley Airport 23 Miles southeast of Bruce Meadows. Their METAR history shows a high of 27 Celsius/81 Fahrenheit for June 30, 2012. Definitely a hot day but was it too hot? The closest I could find on performance data shows a 675 Feet per Minute climb at 75 Fahrenheit at sea level. Thats pretty close to what many small planes of that nature can do, so I took those numbers and transposed them over what a Cessna 172N could do. The 172N has a slighty higher climb performance about 750 for sea level and 75 Fahrenheit, a difference of 75 feet ill subtract out. At 6000 feet at 27C/81F the 172N climbs at 420FPM. Taking out the 75 feet brings it to 345 FPM, now I know this isn't perfect but I'm going with what I have. The plane began its climb out at 1:13 and crashed at 2:55, that leaves 1 minute and 42 seconds in between or 1.7 minutes. 1.7*345 means about 590 feet possible gain. But the plane isn't climbing at its best the entire video, at 2:35 it is apparent something is giving it trouble, that brings it down to about 1.58 minutes climb time which is 545 feet. Theres still another factor to consider and thats how consistent the altitude at the ground was.

The runway at Bruce meadows faces at 05/23 (Northeast/Southwest) but most likely he took runway 23 (Southwest) as immediately to the north east theres a wildlife preserve (Gotta fly at least 2000 feet over it) and he flew straight for quite some time. Although the ground increases in the direction he flew, by how much is difficult using the sectional charts. That means that although he may have been able to climb to about 545 feet higher than his original ground altitude, the ground rose with him and his absolute altitude over the ground would be less than that maximum possible 545. The passenger in the rear reported the plane could only climb to about 60-70 feet above the trees. The trees looked to be around 75-100 but thats still difficult to tell. That would mean according to the passenger they might have only been about 170 feet off the ground. It could still be wildly off as we cant exactly see the altimeter.

Finally theres that disturbance at 2:35 described as a downdraft. It could have been windshear, or a wind effect from the mountains. I don't have too much hands on knowledge of mountain flying so I cant say. If it was windshear he might have suddenly lost a headwind and got a tailwind, screwing up his performance. It could have been a downdraft effect. The actual effect on the aircraft may not have been much (lets say 50 feet) but near obstacles it was definitely enough to have a negative impact.



Summary:

Yes he was flying pretty heavy but he may not have been over the weight limit

The temperature in the area was definitely hotter than standard and the altitude was high, but he still had climbing capabilities within service limits. However he didn't give himself much of a safety threshold.

He might have been able to climb about 545 feet higher than the runway elevation, but the terrain altitude rose in the direction he flew, so his actual altitude over the ground was probably smaller than that.

The disturbance at 2:35 might have been some form of windshear which has the capacity to reduce airplane performance, and with his margins of safety so low already, that could have been the final factor.

Basically he may very well have been flying within the service limits of the aircraft, but the margins of safety he left himself were very low and the decision to fly over obstacles like those trees in that mountain enviroment could be the reason this would be declared pilot error.

Other notes:

The takeoff looks pretty rough but he trying to get off the ground as quickly as he can and ride ground effect until he gets up to speed.

I cant find anything resembling a proper PoH for this aircraft but I did find some data that looks pretty close to it. However this aircraft was a model from the late 40s, so the standards of performance may not be the same as now, and the transcribing I did to the 172N could be thrown off more.

On that note, I do realize that a 172 would have different aerobatic effects with altutude and temperature than a Stinson 108, but its the closest data I could use.

I also couldnt not find balance information to get a rough idea of how the plane was balanced. The type of balance on a plane does have effects on performance.
