Timothy Leland writes that “Spotlight,” the full-time investigative team he created at The Boston Globe 47 years ago, has sponsored its first national investigative project under a fellowship program announced last year. Funded by the producers and creators of the award-winning film of that name, Spotlight Investigative Journalism Fellowships support the research of independent journalists working in partnership with the Globe’s Spotlight Team. Journalists from all over the world submitted ideas for investigations, and in September, based on the work of the winners, the Globe published “Secrets in the Sky,” documenting how easy it is for drug dealers and others with bad intentions to obtain planes and flying licenses in the United States. The report came 16 years after two planes were flown into the World Trade Center by pilot terrorists.
