An aircraft dispatcher describes how weather, war, space launches, and other disruptions can throw airline operations into chaos. In the news, Rolls-Royce on the open-rotor engine design, pilots petition SpaceX Starlink over a price increase, an NTSB board member is fired, Lufthansa changes the carry-on policy for violins, and Barbados controllers stage an unexpected strike.
Guest
Mike Karrels is an aircraft dispatcher and air traffic manager for the Southeast U.S. with a major U.S. carrier, and he’s also a pilot. That combination gives him a unique view of how decisions get made when things don’t go as planned.
Mike describes the aircraft dispatcher as the captain’s partner on the ground. The two share responsibility for operational control of the flight, which means they work together to decide if a flight should continue, divert, or turn back. When an unplanned event hits, the dispatcher is often the first one building the big-picture view: what’s happening, who it affects, and what options are actually realistic.
Sometimes the disruption is regional. An airport closes, weather rolls in, military operations pop up, or a space launch creates airspace that suddenly can’t be used. In those cases, it’s not just about one flight. Crews and aircraft can end up scattered in the wrong places, the passengers need to be taken care of, and the operation has to be reassembled. Aircraft dispatchers and other teams work together to untangle that mess and put airplanes and people back where they need to be.
Other times, it’s just one airplane with a problem. Maybe a mechanical issue, a medical situation, or conditions deteriorating at the destination. The aircraft dispatcher has to make a decision. Divert to another airport? Return to the origin? Each choice has tradeoffs.
Mike walks through the kinds of factors that come into play. Beyond passenger impact and safety, aircraft dispatchers look at things like whether there’s ground staff at the diversion airport, what kind of ground transportation is available, and how quickly the airplane can be turned around and put back into service. Crew duty and rest rules are another major piece: a decision that solves the immediate problem might leave a crew out of legal flying time later, stranding passengers or aircraft.
On top of government regulations, airlines often layer on their own rules. For example, there may be company policies about diverting into an uncontrolled field, even if it’s technically legal. Dispatchers have to navigate both sets of requirements while still making timely decisions in a dynamic situation.
Getting to that level of responsibility takes serious training and certification. Aircraft dispatchers are required to understand aircraft performance, weather, navigation, regulations, and company procedures. They also need to stay aware of the geopolitical environment. Overflight restrictions, conflict zones, and international rules all shape where a flight can and should go on a given day.
Spaceflight adds yet another wrinkle. Mike talks about the Aircraft Hazard Area, or AHA, around space launches: the region where debris might fall if something goes wrong. Those areas can close significant chunks of airspace and affect routes and alternates, even for flights that seem far from the launch site.
Mike owns a share of a vintage 1963 Beechcraft Musketeer. He produced the Flying and Life podcast, where he shared stories and perspectives from both sides of the cockpit door. The back catalog of those episodes is still available for anyone who wants to dive deeper into the world of flight dispatch and everyday aviation life.

Rolls-Royce remains unconvinced that open-rotor benefit outweighs integration risk
What type of engine (or engines) will be offered on next-generation single-aisle aircraft? Will it be an open-rotor (an unducted fan) or a conventional ducted fan engine? What will the airframers want and what will the engine OEMs offer? All those questions are unanswered.
In wind tunnel tests ten years ago, RR looked at open-rotor noise and high-speed performance. More recently, the company validated its previous work and sees propulsion efficiency advantages. RR sees two areas of concern: risk and integration issues.
Integration issues include: engine noise entering the cabin that would have to be attenuated, protecting against a blade-out event, aerodynamic interaction with the wing, and the effect on overall aerodynamics.
Rolls-Royce director of research and technology Alan Newby says the company is unconvinced the open-rotor is the way to go, saying, “I can do windtunnel work. I can do simulations, if you like, and I can go and fly on an A380. But the time you realise whether it works or not is when you run that first engine on your production aircraft. That’s a long way down the road. That discovery of risk is a long time in the process.”
After considering performance and risk, Newby says Rolls-Royce favours the ducted fan configuration: “We’ve gone into it with our eyes open. We’ve looked at the previous data. And, on balance, we’re sticking with what we’ve got. We think it’s the right solution.”
Rolls-Royce makes a play for narrowbody aircraft engines with £3bn UltraFan 30 programme
In February 2026, Rolls-Royce revealed a mock-up of the ducted UltraFan 30 concept with a geared turbofan. The company is looking for up to £200 million in UK government support to help fund development and testing of a scaled demonstrator. More than £500 million has already been invested. The overall program could cost around £3 billion.
The Rolls-Royce UltraFan 30 narrowbody engine is a 30,000 lb thrust-class geared turbofan derived from Rolls-Royce’s UltraFan architecture. It features a 90-inch fan and targets up to 20% better fuel burn than current engines. Ground testing is from 2028, with entry into service targeting 2035.
Pilots Petition Starlink Following Shift to New Speed Tiers
Airlines are switching to SpaceX Starlink service on their airplanes. Many GA pilots use the compact Mini dish and a Roam plan because it gives them the ability to use phone and tablet applications for real-time weather access, flight planning updates, and communications.
SpaceX has changed its Starlink in-motion service offerings, which moves many GA pilots into a higher-priced plan. A change.org petition, Request reinstatement of Starlink roaming plans for pilots has been created and signed by thousands of pilots:
“For those of us in general aviation, Starlink has been nothing short of a revolution. As a general aviation pilot, having Starlink service on board has dramatically enhanced my flying experience, improving not only my situational awareness but also my ability to access up-to-date weather and airport safety information while airborne. These capabilities are critical to ensuring the safety and efficiency of our flights, and allow us to maintain communication with others while traveling, providing peace of mind to both pilots and our loved ones.”
“However, Starlink has recently made the disappointing decision to raise the cost of the plans serving general aviation by 5 times, while providing less than half of the data of the previous plans simply based on the speed that our planes travel. Many of us are not commercial operations nor traveling near the speeds that these plans are targeting.”
“We urge Starlink to reconsider their decision and reinstate the roaming plans with a speed that accommodates general aviation…”
The Current in-motion speed limits for Roam, Local Priority, and Global Priority (land/sea use) are up to 100 mph in motion. Above that, Starlink expects you to move to an aviation plan. The new Aviation 300MPH plan is $250 per month and includes 20 GB of data, with overage billed at $10 per GB. The new Aviation 450MPH plan is $1,000 per month and includes 20 GB of data, with additional data billed at $50 per GB. Includes land and ocean coverage.
NTSB board member Inman says he was fired by White House
A Republican member of the U.S. National Transportation Safety Board said on Sunday he was fired on Friday by the White House without any explanation. Todd Inman, a former chief of staff to Transportation Secretary Elaine Chao, was fired by the White House, at the time without any explanation. Inman had served on the NTSB since April 2024.
White House says NTSB member was fired for inappropriate alcohol use, harassment
After the firing, a White House statement said, “The White House lawfully removed Todd Inman from the NTSB after receiving highly concerning reports of inappropriate alcohol use on the job, harassment of staff, misuse of government resources, and failure to attend at least half of NTSB meetings.
Inman told Politico, “I categorically deny the allegations made in the White House statement. It has become increasingly obvious this action was a political hit job. While not my original intent, I look forward to defending my reputation through all legal means possible.”
Lufthansa Softens Violin Policy After Backlash Over “Naked Violin” Incident
Lufthansa strictly limits carry-on baggage item dimensions to 55 x 40 x 23 cm. At the same time, the airline allows violins and other small musical instruments to travel in the cabin free of charge. However, many standard violin cases are greater than 55 cm in length. That means the options are to check the instrument or purchase a second seat. The classical music community exploded after a viral video of a musician carrying a violin onboard without the case.
Lufthansa now says airline staff can exercise more flexibility to allow small instruments in the cabin. The combined dimensions of the hand luggage cannot exceed 125 centimeters.
In the United States, federal law requires airlines to allow small instruments such as violins onboard if they can be safely stowed in the cabin. Europe has no equivalent rule, leaving each airline to develop its own policy.

Multiple Planes Performed ‘Flights to Nowhere’ After Air Traffic Controllers Stage Shock Walkout
After an unsanctioned strike by air traffic controllers, the Barbados Ministry of Tourism and International Transport said that the airspace over the country was shut down for about seven and a half hours. The March 7, 2026, job action left passengers at the island’s Grantley Adams International Airport stranded. The controllers were protesting a number of grievances, including staff shortages. These have caused controllers to assume additional responsibilities without extra compensation.
An emergency meeting was held with the Barbados Workers’ Union and the National Union of Public Workers, which represent air traffic controllers. They returned to work, and another meeting is scheduled for March 11, 2026.
Delta, United, Air Canada, JetBlue, and WestJet flights to Barbados were impacted.
