Aircraft Information
- Airline: United Airlines (operated by a regional partner)
- Flight Number: 4339
- Aircraft Type: Embraer ERJ-145
- Origin: Dulles International Airport (IAD)
- Destination: Roanoke-Blacksburg Regional Airport (ROA)
Emergency Stopping Equipment Engaged
The jet ultimately came to a halt in an "engineered materials arresting system" (EMAS). This system is designed to safely stop aircraft that overrun runways. It consists of crushable materials that deform under the weight of an aircraft, providing a controlled deceleration.
According to the Roanoke-Blacksburg Airport, the plane ended up specifically in the EMAS located at the end of runway 16-34. The successful deployment of this safety feature prevented a more severe outcome, ensuring the safety of all individuals on board.
What is EMAS?
An Engineered Materials Arresting System (EMAS) is a safety area at the end of some runways. It is made of lightweight, crushable concrete blocks designed to safely stop aircraft that overrun the runway. When an aircraft rolls over the EMAS, the blocks collapse, absorbing the plane's energy and bringing it to a controlled stop, significantly reducing the risk of injuries or major damage.
Response and Passenger Transfer
Following the incident, airport staff and Roanoke City first responders immediately mobilized. Their primary focus was to ensure the safety and well-being of everyone involved. Passengers were assisted off the aircraft and transported to the airport terminal.
The prompt response from emergency services and airport personnel was critical. Their coordinated efforts helped manage the situation efficiently and provide necessary support to the passengers. No reports of panic or distress were made during the transfer process.
"No injuries were reported and the Federal Aviation Administration will investigate what happened," Virginia State Police confirmed on Thursday morning.
Airport Operations and Delays
Immediately after the incident on Wednesday night, the airport's runways were closed. This measure is standard procedure to allow for emergency response and initial assessment of the scene. The closure impacted subsequent flight operations at Roanoke-Blacksburg.
As of Thursday morning, some runways remained closed. The airport advised travelers to check directly with their airlines for the most current information regarding flight statuses. This closure led to potential delays and cancellations for passengers scheduled to fly in or out of ROA.
- Wednesday Night: All runways closed temporarily.
- Thursday Morning: Some runways reopened, others remained closed.
- Passenger Advisory: Contact airlines for flight updates.
Investigation Underway
The Federal Aviation Administration (FAA) has announced it will conduct a full investigation into the runway overrun. FAA investigations typically examine multiple factors, including pilot actions, aircraft performance, air traffic control directives, and runway conditions.
The National Transportation Safety Board (NTSB) may also become involved, depending on the severity and nature of the incident. These investigations are thorough and aim to determine the exact cause of the event, ultimately leading to recommendations for preventing similar occurrences in the future.
The safety of air travel relies heavily on these detailed analyses. Findings from this investigation will be crucial for understanding why United Flight 4339 overshot the runway and what preventative measures could be implemented.
Impact on Travelers
Travelers planning to use Roanoke-Blacksburg Regional Airport should continue to monitor airline announcements. While the immediate danger has passed, operational adjustments can affect schedules for several days. Passengers are encouraged to allow extra time for travel and reconfirm flight details before heading to the airport.
This incident highlights the importance of airport safety systems like EMAS. It also underscores the diligence of emergency responders and airport staff in handling unexpected aviation events.
