The Air Current - Jon Ostrower

Something is going on with Runway 10L at Palm Beach International Airport in Florida. Last week, a Bombardier-built CRJ200 on final approach had the strangest thing happen.

The aircraft’s radar altitude abruptly ran down to zero, causing repeated loud aural warnings: PULL UP WHOOP WHOOP DON’T SINK TOO LOW GEAR.

The incidents were reported to the Federal Aviation Administration.
