Guest



Stephen Osborne is the owner and founder of Top Aviation Services and the president and CEO of The Osborne Company. Shortly after planemaker Sonex shut down, he purchased its assets and reopened operations as Sonex Aviation LLC.


Sonex has a history of providing the recreational aviation community with innovative and affordable aircraft kits, powerplants, and accessories. The company is a leader in the homebuilt space and works to cultivate new pilots and airplane builders through educational efforts.


Stephen describes how he quickly moved to purchase the Sonex assets, resume shipping kits, and set the tone for the company’s future. Sonex has a strong “work family” environment that serves not only employees but also customers and vendors. As Sonex moves forward, its success will be built on those core values and the mission to make aviation affordable for everyone.


Stephen is a military veteran and former U.S. Army Captain and FAA-certificated commercial pilot. Top Aviation provides FAA-certified flight training for Private Pilot, Instrument Rating, and Commercial, as well as discovery flights and aircraft rentals at KTOP in Topeka, Kansas. The Osborne Company is a general contracting firm specializing in the design and installation of electric vehicle and aircraft charging infrastructure across the United States.

Feds Mull Pulling Customs From New York, LA, Chicago, and Other Airports in ‘Sanctuary Cities’

Homeland Security Secretary Markwayne Mullin has suggested removing Customs and Border Protection officers from airports in so-called sanctuary cities where local authorities do not assist federal immigration investigations. Those cities include New York, Los Angeles, Chicago, and San Francisco international hubs. In a recent congressional hearing, Transportation Secretary Sean Duffy said, “We shouldn’t shut down air travel in a state that doesn’t agree with our politics.”


Airlines and business groups warn of chaos if US restricts international flights

In a joint statement, the U.S. ​Chamber of Commerce, Airlines for America, the National Retail Federation, U.S. Travel, and other groups said the move “threatens to cause unnecessary chaos throughout the nation’s air transportation system.”


“Any reduction in Customs and Border Protection operations at major U.S. gateway airports threatens to cause unnecessary chaos throughout the nation’s air transportation system. International aviation networks are highly interconnected, and operational changes at a small number of gateway airports will quickly ripple across the country, negatively impacting travelers, cargo shipments, supply chains, and the communities that depend on those connections. Airports and airlines rely on stable, predictable federal inspection services to keep people and commerce moving safely and efficiently. We urge DHS to avoid actions that would create unnecessary operational and economic consequences for communities nationwide. As the United States prepares for growing international travel demand, DHS should avoid actions that would create unnecessary bottlenecks and economic consequences for communities across the country. Now is the time to strengthen America’s gateway infrastructure, not weaken it.”

Spitfire could return to production 90 years after first flight

An original Supermarine Spitfire will set you back about £3 million. The new Aerolite Spitfire Type 433 has been constructed at a cost of about £750,000. The composite kit plane is touring the UK this spring and summer at air shows and military and classic motor festivals.


Great British Supermarine Ltd, is the manufacturer. Chief executive Jeremy Meeson, said: “The moment is right to reimagine the Supermarine Spitfire because today’s materials, propulsion, and digital engineering finally let us evolve an icon without losing what made it exceptional.”


A PDF let the internet hear the final words in the cockpit of a UPS plane as it crashed. The NTSB now wants it taken down

The NTSB does not release cockpit voice recordings made during an accident. Other evidence from investigations is released to the public, including photographs, videos, maps, and other data. During a two-day investigative hearing on the UPS flight 2976 accident, a PDF file was released that showed an analysis of the spectrogram of the audio recorded by the CVR.


However, the NTSB was not aware “that advances in image recognition and computational methods have enabled individuals to reconstruct approximations of cockpit voice recorder audio from sound spectrum imagery.” Subsequently, the NTSB closed public access to all dockets.
