We congratulate our friend Carlos on his new book. “They Flew: A History of the Impossible.” Like 14,000 other kids, Carlos Eire came to the U.S. in what we would later call the “Pedro Pan” program. He settled in Illinois and eventually became a professor at Yale. This is his story. A few months ago, we spoke with Carlos about the 20th anniversary of Babalu and “Waiting for snow in Havana,”, a book that your kids should read.
