A plane and a helicopter crashed.

They say this helps safety.

Mr. Duffy has a big plan for planes.

The system is old. It cannot handle many planes.

We don't know if the plan is good.

We fix it. We make new for you and your family.

We don't know much.

The system worked. It was okay. But not good for planes. People's lives are important.

Jacobson does not think Duffy's idea is good. Two planes had problems. Maybe people will like his idea now.

The airplane system has problems.

The old system is not good.

A man from a plane group told the government. Airports use old wires. New wires are better. Old wires make planes stop. This happened in Newark.

A machine helps planes go in and out of an airport. This machine did not work for a short time. Maybe old wires were the problem. People need this machine to help planes.

Big boss says: New wires for old. More data lines. More workers.

He wants Newark to be good in summer.

Flights at Newark Airport are slow. Some flights stop. This is to be safe.

Planes have a system to show where they are. This system helps planes and people on the ground. A helicopter did not use this system when it crashed.

Duffy helps people get jobs to control airplanes.

It is hard to make the airplane system better. The old system must work. A new system is needed. It is hard to change to the new system. So, they made small changes before.

It is a hard problem. It needs money and good managers.
