Secretive Russian-Made Mi-17 Helicopter Makes Unusual Appearance In Tucson
Residents of the Tucson, Arizona area were startled earlier this week by a group of helicopters, including at least one Russian-made Mi-17 Hip, making very low nighttime flights as part of what turned out to be a U.S. military exercise. This kind of domestic urban training is not uncommon, especially for U.S. special operations forces, and often comes at least as a surprise to bystanders. However, this instance is notably out of the ordinary in that the helicopters look to belong to a particularly shadowy unit.
Imagery of the helicopters flying over Tucson first began to emerge on social media on the night of June 17-18. The Pima County Sheriff's Department subsequently confirmed to local media that the helicopters, one of which was an Mi-17 with an overall gray paint scheme, were affiliated with the U.S. military. The grounds of an abandoned school were used as part of the training exercise.
Why are these helicopters flying around the south side this low and with no lights? And being followed? Escorted? Been over an hour. What is happening?? @whatsuptucson @TmzTucson @DanMarriesKOLD @Mary_reports @kgun9 @KVOA @KOLDNews @Tucson_Police pic.twitter.com/hpSFLhcg8d

'The only thing I knew was that there was a lot of noise, flash bangs, helicopters, personnel, lights, sirens, that type of stuff,' Pima County Sheriff Chris Nanos, who was apparently unaware that this week's exercise was set to occur, told KOLD News 13, a local CBS-affiliated television station yesterday. 'From my understanding, we didn't even train. We were just there to assist the DoD in their training efforts.'
'When he looked into it, he found out his SWAT team facilitated the location with the Department of Defense to use solely for their training weeks ago,' KOLD's report added. 'I will not blame DoD. I will not blame South Tucson. This was on us. We could easily have said, use our location (elsewhere) at 10 p.m., I don't understand what the thinking was there.'
Nanos apologized for the lack of communication with the public and pledged not to let a similar incident happen in the future.
TWZ has reached out to the Pima County Sheriff's Department and the U.S. military for more information.
As it turns out, an additional video, seen below, was posted on Instagram on June 17 showing what looks to be the same gray Mi-17 flying together with a trio of Bell 407 helicopters just outside Tucson. There was also a sighting of an identical-looking Hip at Pinal Airpark northwest of Tucson earlier this month.
For all those wondering what's flying around lights off around Tucson last night. 3 ATO Bell 407s trailed by their Mi-17 flying yesterday near Tucson, Arizona. The grey Mi-17 was also spotted at the local airport.

I've compiled information on the DoD training that occurred in Tucson, AZ on the 17th of June into a briefing document on my Obsidian Vault.It is written with a focus on the involvement of the Army's Aviation Technology Office and their use of Mi-171Es.https://t.co/OuFqI4oiHZ pic.twitter.com/qrrYGZhxsa

Whether or not it may have been a factor in the lack of advance notice to the public or Sheriff Nanos about the exercise, the gray Mi-17 seen during the exercise is a dead ringer for Hips tied to a highly secretive U.S. Army element known as the Aviation Technology Office (ATO). Previously known as the Flight Concepts Division (FCD), ATO is headquartered at Felker Army Airfield, which is part of Fort Eustis in Virginia.
In addition to gray-painted examples, ATO-linked Mi-17s have also been seen painted tan and wearing a tan-and-brown camouflage scheme. These helicopters have a distinctive configuration that includes a nose-mounted weather radar, a sensor ball turret under the right side of the cockpit, supplemental armor panels around the front, a large particle separator in front of their engine intakes, and various antennas on the fuselage and tail boom.
From FB: "This was taken by a friend of mine who works at Pinal Airpark a week and a half ago it is an MI-17 Helicopter that is operated by the US Government. DOD to be exact. The helicopter came in broad daylight and is flying out of Pinal for these exercises" pic.twitter.com/FIDUamk4fT

ATO is understood to operate several Bell 407s in a configuration that aligns with what can be seen in the recent video shot outside Tucson. Both types were notably seen together at a farm in North Carolina back in May 2021 after the Mi-17 made an emergency landing there. The Bell 407 brought in additional personnel and repair parts to get the Hip airborne again, as you can read more about here.
In January 2021, Bell 407s likely belonging to ATO had also been spotted flying around Los Angeles and other nearby locales, conducting what appeared to be urban training that included touch-and-goes on helipads on top of a number of buildings. TWZ reported on those sightings at the time.

Gray-painted Mi-17s with the same general configuration were also spotted in North and South Carolina in separate instances last year.

As already noted, U.S. special operations forces, in general, regularly train in and around cities and towns across the United States, including for air assault missions. Doing so offers valuable real-world opportunities to hone important skill sets that cannot otherwise be replicated to the same degree with dedicated urban training facilities. This includes the fact that these are 'live' locations full of real hazards and neutral bystanders. At the same time, poor and/or short-notice communication with the public, as well as more serious screwups, have caused controversy around these kinds of training events, which can also involve automatic guns firing blank rounds and simulated explosive devices, on multiple occasions in the past.
When it comes to ATO (and FCD before it), specifically, it remains one of the most secretive aviation units within the U.S. military. From what is known publicly, it specializes in providing discreet aviation support for covert and clandestine operations, and also has a bleeding-edge developmental function. For instance, ATO/FCD is understood to have been involved with the development of the stealthy derivatives of the UH-60 Black Hawk helicopter employed during the 2011 raid in Abbottabad, Pakistan, that led to the death of then-Al Qaeda leader Osama Bin Laden.
It is worth noting here that the U.S. Central Intelligence Agency (CIA) also has a long history of operating Mi-17 variants, including through various secretive contractors. CIA-linked Hips were very visibly active as part of evacuation operations in Afghanistan after the fall of the capital Kabul to the Taliban in August 2021.
We found (and corroborated with flight data) that one of the Mi-171E helicopters was inadvertently captured in a livestream by @MARCATV, a Spanish news outlet, as it flew from HKIA to the CIA compound toward the compound on Aug. 20. pic.twitter.com/lG1qVi0qHY

Other less secretive elements of the U.S. military also make use of contractor-operated Mi-17s, as well as other foreign fixed-wing aircraft and helicopters, for training and evaluation purposes. The Hip is in widespread use globally in a wide variety of configurations, including heavily armed transport types. It is a design American forces regularly encounter in service with allies and partners, and that is also part of the potential threat picture for operations worldwide.
Still, the particular features of the gray Mi-17 seen this week in the Tucson area, together with the Bell 407s, point most strongly to ATO.
Whether or not more details emerge about the recent urban training exercise in Tucson, Arizona, the participants in this case look to have been particularly unusual.

Teen boy killed in fiery multi-vehicle crash in Pompano Beach, 5 others hospitalized, BSO says
A teenage boy is dead and five people were hospitalized after a fiery crash involving multiple vehicles in Pompano Beach on Friday night, authorities said. Just before 8 p.m., the Broward County Sheriff's Office responded to a multi-vehicle crash and car fire near 200 West Copans Rd. According to investigators, the preliminary investigation revealed that a 2019 Mercedes-Benz CLA 250, which a 16-year-old boy drove with a 17-year-old female passenger and three 17-year-old male passengers, was traveling west on West Copans Road and approaching Leisure Boulevard. Meanwhile, a 2021 Toyota Sienna, driven by an 82-year-old man, was traveling south on Leisure and approaching West Copans. BSO detectives said that at some point, the Sienna turned left when it collided with the Mercedes. The collision caused the teenage boy to lose control of his car, which rolled onto its roof as it slid southwest across the road and into eastbound traffic, colliding with a 2015 Lexus RX 350. Also, BSO said a 2021 Toyota RAV4 was traveling east on West Copans and was struck by debris as the Mercedes slid by. BSO deputies at the scene began life-saving measures until Pompano Beach Fire Rescue arrived and took all the Mercedes' occupants and the Lexus' driver to the hospital for treatment. However, the 16-year-old boy died at the scene, BSO said. BSO said the Sienna and RAV4 drivers were not injured and remained at the scene and cooperated with investigators. According to BSO, detectives said excessive speed may have been a contributing factor, but the circumstances surrounding the crash remain under investigation.

The sculptures worth $2.1 million stolen from Anaheim warehouse have been found
A pair of sculptures that were taken from a warehouse in Anaheim last week have been recovered, according to authorities. The Anaheim Police Department confirmed that the sculptures, worth an estimated $2.1 million combined, were found Friday night. They were found in a trailer in a driveway after community members tipped police off to the location. Masterpiece Publishing Created by Sir Daniel Winn, the two pieces of artwork went missing sometime before June 9, police said. They each stand higher than eight feet tall and weigh thousands of pounds. Police said it's possible that forklifts were used to steal the sculptures due to their weight. As of Saturday, there's no word on any potential suspects in the alleged burglary. No arrests have been made, police said.

Colorado dentist sentenced to over three years in prison for multi-million dollar tax evasion scheme
A dentist in northern Colorado was sentenced to over 3 years in prison this week for concealing millions in an illegal tax shelter. According to authorities, Ryan Ulibarri, who owned and operated Ulibarri Family Dentistry in Fort Collins, purchased an abusive-trust tax shelter in 2016. Ulibarri used the tax shelter to conceal income and create false tax deductions through trusts and a foundation that he created and controlled. The Department of Justice said Ulibarri signed trust instruments that named him as a trustee of three trusts and a foundation, and then opened bank accounts in the name of each. Authorities said he recruited friends to falsely sign the trust instruments as the creators of the trusts in order to hide the fact that he created them. Despite being warned by attorneys and CPAs that a trust in Colorado can't own a dental practice, he transferred the majority ownership of his dental practice to his business trust. Through the tax shelter, Ulibarri concealed over $5 million in income from his dental practice from the IRS and evaded paying more than $1.6 million in federal and state income taxes owed on it. Authorities said he transferred the income into the various trust and foundation accounts to make it appear the money didn't belong to him, then used those funds to pay for personal expenses, including his mortgage, credit card bills, boats, luxury vacations and professional baseball season tickets. Ulibarri also filed false tax returns for himself, his practice, the trusts and the foundation with fraudulent deductions. The DoJ said he disguised personal living expenses as trust expenses and charitable donations. On Wednesday, Ulibarri was sentenced to 41 months in prison for tax evasion. He was also ordered to serve three years of supervised release and to pay a $150,000 fine. Ulibarri must pay $1,449,121 in restitution to the IRS and $166,966 in restitution to the Colorado Department of Revenue as well.
