This week’s broadcast of Peter Greenberg Worldwide is from 360 Chicago in Chicago, with arguably the best views of the city — and a great experience. I have all the updates, including why American Airlines is suddenly asking 1,500 flight attendants to take unpaid leaves. And are your cellphone texts safe from scrutiny by authorities when you return to the U.S.? Then a deep dive into Chicago from the 94th floor of the original John Hancock Center. PBS host Geoffrey Baer, and “Chicago’s best tour guide,” traces the city’s rise as the birthplace of the skyscraper and takes us inside the newly opened Obama Presidential Center. Sam Strange, of Young & Strange, Champions of Magic, pulls back the curtain on Chicago’s rich magic history and his summer-long run at the Studebaker Theater. Ryan Culligan, Architect and Design Partner at Skidmore, Owings & Merrill, discusses engineering the Hancock Center against Chicago’s fierce winds and his work reimagining O’Hare’s Terminal 1 for a more frictionless flying experience. The Polish population of Chicago is the largest outside of Warsaw, and Thomas Swick, Author of Falling into Place: A Story of Love, Poland, and the Making of a Travel Writer, shares how his romance in 1980s Warsaw during the rise of Solidarity shaped his life as a travel writer. Leigh Barnes, President of Intrepid Travel Americas, unpacks the year’s biggest travel trends, from “coolcation” shoulder-season trips to the rise of bucket-list adventures like gorilla trekking and Everest Base Camp. There’s all this and more on this edition of Peter Greenberg Worldwide.
