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.”

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.
