It’s been so long since the last Super Bowl in South Florida that fast-evolving technology has forced a lot of changes in security preparations for Super Bowl LIV at Hard Rock Stadium a week from Sunday.

In 2010, when the New Orleans Saints beat the Indianapolis Colts and The Who performed at halftime, one of the big concerns from the sky was actually big, slow blimps.

Now, it’s much smaller, swifter drones. During last year’s Super Bowl in Atlanta, for instance, six drones flying too close to the stadium throngs were reportedly confiscated in the days before the games.

Federal and local authorities say they have a plan to combat the new threat if it ever appears but, for security purposes, they aren’t willing to share it with the public. But one federal employee familiar with defense and security systems being employed for the Super Bowl said if a drone appears that is perceived in any way as a threat it will be taken care of through “drone mitigation technology.”
