The next time you’re driving by a crane and think to yourself, “Wow, that thing is really high,” you’re not alone. There are so many types of cranes available, with a range of heights from a few dozen feet to others that reach the tops of towering skyscrapers. Three such cranes in San Diego recently had to be adjusted because the Federal Aviation Administration ruled they posed a safety hazard to airplanes.

The cranes in questions are part of an ongoing construction project to expand a courthouse in downtown San Diego. Exactly what problem does the FFA think the cranes are causing? According to the administration, they could cause air traffic to clog in the area, or worse yet, actually cause a crane to clash. Fortunately, an agreement has been met and the contractors responsible for the cranes will be making a few adjustments.

In order to ensure the cranes are not causing any safety issues for nearby airplanes, they will now be equipped with both flags and lights to alert pilots of their presence. In addition, their maximum heights have been lowered to ensure no plane will be crossing paths with any one of them.

Unfortunately, there is a lawsuit involved and the issue doesn’t appear to be completely over. The contractors argue they need the planes at a specific height (around 600 feet) to complete the project. So far, the judge has noted that the contractor’s compliance with the FAA’s demands shows they are willing to work with them.
