B-52 in the air

Introduced to the US military more than 70 years ago, the venerable B-52 Stratofortress bomber has again taken to the skies -- this time against ISIS targets in Iraq and Syria.

The behemoth proves that old doesn't have to mean outdated, even in an era of rapid change. Just the opposite: Through good maintenance and recent high-tech updates, this vintage plane more than holds its own against newer designs.
