If you live near Northwest 70th and O streets just outside of Lincoln, you probably heard the buzz of a helicopter throughout the day.

LES is having work done on some of their towers, stretching 23 miles across Nebraska.

The project starts at Northwest 68th street and Holdredge and ends at the Mark T. Moore substation near Hallam.

But what's possibly most impressive about the project, is the men completing it.

While you may feel the need to re-fuel during a tough day of work,
filling up the tank keeps the five man crew of AIR2, in business.

"They are replacing the insulators in our 345,000 volt line that goes from Northwest 68th and down to Hallam," says Bill Gardner, a project inspector for LES.

And the crew, uses special transportation to do so.

Ferried by helicopter, they're replacing 500 defective insulators in LES transmission towers - towers reaching 135 feet from the ground.

"I mean looking from here it looks dangerous but its really not. We're all used to it. We all go through training, " says the project's lead lineman, Marty Lyons.

For Lyons, it's all about the routine.

From climbing off the helicopter hundreds of feet up - to finding the right step on a ladder they hang while in mid air. Exciting moves at first, he said.

"Like when I first started, it was probably a month and it was really an adrenaline rush."

But, Lyons said that rush fades away.

"Once you get used to it, it's just like everything. Once you get used to it," said Lyons

While Lyons may debate whether or not his job is dangerous, what's certain is that his job helps keep you safe.

The insulators they're replacing are what hold up the electric wires and if the insulators fail, it could be a very dangerous situation.

"The worst case scenario, and that's what you always have to look at with utility, is if an insulator were to fail, it could potentially drop the wire down to the ground," said Garnder.

It's a risk LES isn't willing to take. Engineers found one insulator with a problem last fall and it created enough concern for public safety that the company decided to replace all the insulators along the 23 mile line of towers.

Garnder says safety and reliability are top priorities for LES.

Still, Lyons says his job is like any other. And from lift off to landing, it's just another day.

The crew working on the transmission towers works for a contractor based out of Maryland.

They'll work seven days a week for about six weeks to complete the project.

LES says funding for the work was planned for and that customers will not experience any sort of service disruption.
