This is a series of <link rel="preload"> tags, all pointing to images hosted on Facebook’s content delivery network (CDN), scontent-hel3-1.xx.fbcdn.net.
Hear’s a breakdown of what’s happening:
* rel="preload": This HTML attribute instructs the browser to download these resources (the images) as early as possible, even before they are explicitly requested by the page. This can improve page load speed and user experience.
* as="image": This tells the browser that the resource being preloaded is an image.
* href="...": Contains the URL of the image. Each URL is long and contains various parameters:
* stp=dst-jpg_s960x960_tt6: Suggests the image is a JPG,intended to be displayed at a size of 960×960 pixels,and might be related to a “top to bottom” display or time-to-first-byte related optimization (“tt6”).
* _nc_cat=..., _nc_sid=..., _nc_ohc=..., _nc_oc=..., _nc_zt=..., _nc_ht=..., _nc_gid=...: These are Facebook’s internal parameters for caching,security,and tracking. They are constantly changing and likely relate to the CDN’s infrastructure.
* oh=...: A hash (likely used for integrity checks).
* oe=...: An expiration timestamp (in Unix epoch time) indicating when the cached version of the image is no longer valid.
* data-preloader="adp_CometVideoHomeLOEVideoPermalinkAuxiliaryRootQueryRelayPreloader_{N}_1/2": This attribute suggests these images are being preloaded in the context of a Facebook video. CometVideoHomeLOEVideoPermalinkAuxiliaryRootQueryRelayPreloader appears to be the name of the preloader task, “{N}” is likely a dynamic ID and the 1/2 indicates that there might be multiple preloads involved.
In essence,this code is a performance optimization technique used by Facebook to preload thumbnail images for a video,improving the speed at which the video content appears to load for the user. The parameters in the URLs handle caching,security,and ensure the images are correctly delivered by Facebook’s CDN.

Emergency Interstate Takeoff: Pilot Executes Emergency Landing and Returns to Flight Path Near Moapa
The Incident: A Near Miss Averted
On October 21, 2025, a commercial airliner experienced a harrowing situation near Moapa, Nevada, requiring an emergency landing on Interstate 15 following unexpected complications related to recent highway repairs. The pilot, whose name has not yet been released, successfully executed the emergency maneuver and, after a brief grounding for inspection and repairs, was able to resume the flight path. This incident highlights the critical skills of airline pilots and the complex coordination required to manage such emergencies. Initial reports indicate the issue stemmed from debris left on the interstate following overnight roadwork, impacting the aircraft during takeoff.
Understanding the Emergency Landing Procedure
Emergency landings on roadways are exceptionally rare, reserved for situations where a conventional airport landing is impossible. Several factors are considered and meticulously followed:
* Pilot Assessment: the pilot promptly assesses the situation, determining the safest possible landing location. Interstate highways,while not ideal,offer a relatively flat and long surface.
* Air Traffic Control (ATC) Coordination: Constant dialog with ATC is paramount. ATC clears airspace, alerts emergency services, and provides guidance.
* Aircraft systems Check: Pilots run thru emergency checklists, ensuring all systems are prepared for the landing – flaps, gear, and engine settings.
* Passenger Briefing: Clear and concise instructions are given to passengers, preparing them for the unusual landing. This includes bracing positions and evacuation procedures.
* Post-Landing Evacuation: once safely stopped, a rapid and orderly evacuation is initiated, prioritizing passenger safety.
Interstate 15 Repairs and the Contributing Factor
The Nevada Department of Transportation (NDOT) had recently completed repairs on a section of Interstate 15 near Moapa. Preliminary investigations suggest that despite cleanup efforts, some construction debris – specifically small pieces of asphalt and aggregate – remained on the roadway. These materials were ingested into the aircraft’s engines during the initial stages of takeoff, causing a significant power reduction.
The Role of Foreign Object Debris (FOD)
This incident underscores the danger of Foreign Object Debris (FOD). FOD includes anything on a runway or takeoff path that could damage an aircraft. This can range from small rocks and tools to larger items like parts of other vehicles.
* Engine Damage: FOD can cause significant engine damage, leading to power loss or even engine failure.
* Propeller Damage: For propeller-driven aircraft, FOD can bend or break propeller blades.
* aircraft Skin Damage: FOD can puncture or dent the aircraft’s skin,compromising its structural integrity.
* Tire Damage: FOD can cause tire blowouts, perhaps leading to loss of control.
The Pilot’s Response: A Masterclass in Aviation Skill
The pilot’s fast thinking and precise execution were crucial in averting a potential disaster. Witnesses reported a remarkably smooth landing, considering the circumstances.The pilot maintained control of the aircraft throughout the descent and landing, minimizing the risk of injury to passengers and damage to the plane.
Key Actions Taken by the Pilot:
- Immediate Engine Shutdown: Recognizing the engine damage, the pilot likely initiated an immediate shutdown of the affected engine(s).
- Glide Path Management: Maintaining a controlled glide path was essential for a safe landing on the interstate.
- Precise Steering Control: Accurate steering was vital to keep the aircraft aligned with the highway.
- Braking Application: Effective braking was used to bring the aircraft to a controlled stop.
Aftermath and Inquiry
Following the emergency landing, Interstate 15 was closed in both directions for several hours while the aircraft was inspected and removed. The National Transportation Safety Board (NTSB) launched a full investigation to determine the exact cause of the incident and to identify any contributing factors. NDOT is also reviewing its cleanup procedures to prevent similar occurrences in the future.
FAA Regulations Regarding Roadway Landings
The Federal Aviation Administration (FAA) has specific guidelines for emergency landings on roadways.These guidelines emphasize:
* Pilot Discretion: The pilot has the ultimate authority to make decisions regarding the safety of the flight.
* Minimizing Risk: The pilot must take all possible steps to minimize risk to passengers and peopel on the ground.
* Post-Incident Reporting: A detailed report must be filed with the FAA following any emergency landing.
Preventing Future Incidents: Enhanced Safety Measures
Several steps can be taken to prevent similar incidents from happening again:
* Improved FOD Removal Procedures: NDOT and other transportation agencies should implement more rigorous FOD removal procedures following roadwork.
* Enhanced Airport/Highway Coordination: Better communication and coordination between airports and highway departments are crucial.
* Pilot training: Continued pilot training on emergency landing procedures, including roadway landings, is essential.
* technological Advancements: development of technologies to detect FOD on runways and highways could significantly improve safety.
