The inconveniences and hassles associated with air travel these days — removing shoes and liquids at airport security checkpoints, for example — are here to stay, said John Pistole, chief of the Transportation Security Administration, on Friday.

Pistole appeared at the Aspen Security Forum, which wrapped up Saturday in a one-on-one interview with ABC “Nightline” co-anchor Terry Moran. He spent more than an hour explaining the TSA’s missions and vulnerabilities before a packed audience at the Aspen Meadows’ Doerr-Hosier Center.
