As a passenger jet headed down the runway toward the runway at New York's LaGuardia Airport, it had to slam the brakes earlier this month as another plane was still on the runway, Renee Hoffer, and all other passengers were thrown into their seats.

On May 6, the day after her disappearance, Hofff was injured in the emergency room because her neck began to hurt and her left arm was numb.

"Stop is as difficult as any car accident I have," Hover said.

The Federal Aviation Administration and the National Transportation Safety Commission said Monday they are investigating incidents where Republican Airlines planes must stop taking off and slammed as a United Airlines plane still taxied across the runway. Even though the airport is equipped with advanced surface radar systems, close calls are still occurring in cases where such close calls are designed to help prevent such close calls.

In the audio of the tower obtained by ABC from the website www.liveatc.net, the air traffic controller told the pilot of Republic Airways Jet: "I'm sorry, I think Manchester United has cleared it before that."

After the controller instructs Republic Airlines to take off, a different RF ground controller takes the Manchester United plane to the new taxi lane because it misses the first exit runway it should use.

When passengers got off the plane after approaching the phone at 12:35 a.m., Hoff said the gate agents refused to even give them a one-night hotel voucher because they blamed the weather, even though another passenger said she had an app on her phone showing another plane on the runway.

Hoff said she has been in a customer service nightmare since the republic's planes operated for American Airlines abruptly ended. She said neither the airline nor the FAA answered her complaint, and she continued to pinch the nerves on her neck as determined by the emergency doctor.

Both the airline and the airport handed over the issue to the FAA.

In recent years, the number of close calls has attracted serious attention from the FAA, NTSB and other security experts. The NTSB's investigation of the close call in Austin in February 2023 highlights these issues, but there are many other high-profile people nearby. In one case, Southwest Airlines jets sailed into a Chicago landing, nearly avoiding crashing into a business jet that crossed the runway.

Laguardia is one of only 35 airports in the country, equipped with the best technology from the FAA to prevent such runway invasions. The ASDS-X system uses various technologies to help the controller track aircraft and vehicles on the ground. At the other 490 U.S. airports with control towers, air traffic controllers must rely on more low-tech tools, such as binoculars, to track aircraft on the ground, because the system is expensive.

If Congress signs his multi-billion dollar plan to a nationwide air traffic control system, expanding the system to more airports is what Transport Secretary Sean Duffy wants to do.

But it is obvious that the technology is not perfect as close calls continue to happen. The FAA is taking many other steps to try to reduce the number of close calls and plans to install additional warning systems in Laguardia in the future.

However, over the decade, the rate of runway invasions per 1 million takeoffs and landings has remained at around 30. The FAA said the rate was as high as 35 in 2017 and 2018. This figure hit 22 times in 2023, but fell to only 7 last year.

To help, there are some efforts to develop a system that will directly warn pilots about traffic on the runway, rather than warning the controller and relying on them to deliver warnings. This can save precious seconds. But the FAA has not yet proved that the system directly warns Honeywell International that it has been developing for years.

The worst accident in aviation history occurred in 1977 on Tenerife, Spain, when the KLM 747 began taking off while the Pan AM 747 was still on the runway. When the plane collided in thick fog, 583 people died.
