Bad crashes happened. Planes hit in the sky. Now they fix old system. They need more people for planes.

This makes it safe. It stops problems at the airport.

Sean Duffy has a big plan for airplanes.

Airplanes fly. It is hard for old system. Many flights.

We do not know if the plan is good. Some people say it is needed.

We will fix it.

We do not have many details.

People's lives are important.

Jacobson does not like Duffy's idea. Maybe more people will like it now. There was a crash in Washington D.C. A plane hit a helicopter. There was also a problem with a plane in Toronto.

Airplanes have problems.

The system is old. We need to make it new.

Old wires cause problems for planes.

Big machines help planes fly. One machine in Philadelphia stopped working. It helps planes go to Newark airport. The machine uses information from New York. Some lines from New York are old. People who help planes moved from New York to Philadelphia.

The FAA will change old wires. They will add new lines.

Newark will be better in summer.

Planes go slow at Newark airport. Many flights are cancelled.

Planes see other planes better now.

Duffy helps air traffic controllers. They get jobs faster. They do better in school. The FAA gives money to old controllers. They stay at work.

It is hard to make airports better. We use the old system. We make a new system. It is hard to change.

It is a hard problem. It needs money. It needs good people.
