Based on the information provided, it is difficult to determine the exact type of aircraft or object that would have two white lights side by side, sit stationary for over 5 minutes, and make no noise. However, there are a few possibilities to consider:
Helicopter: Some helicopters have white lights mounted on their fuselage or wings. They can hover in place and remain stationary for extended periods. However, helicopters typically produce noticeable noise, although it can vary depending on the distance and atmospheric conditions.
Unmanned Aerial Vehicle (UAV) or Drone: Drones come in various sizes and configurations. Some consumer or commercial drones have white lights for navigation or to enhance visibility. Drones can hover in place and make little to no noise, especially at a distance. However, the specific characteristics of the lights and their distance apart would depend on the particular drone model.
Light aircraft or general aviation aircraft: Certain small aircraft, such as private planes or light sport aircraft, may have white lights on their wings or fuselage. However, these aircraft are typically in motion rather than stationary for extended periods. Additionally, light aircraft often produce audible noise, though it might not be as pronounced as that of larger commercial jets.
Unidentified Flying Object (UFO): If the lights do not correspond to any known aircraft or objects, the possibility of an unidentified flying object (UFO) cannot be ruled out. UFO sightings often describe objects with unusual characteristics or behaviors that do not match conventional aircraft. However, it's important to note that a UFO simply refers to an unidentified object and does not necessarily imply an extraterrestrial origin.
To accurately identify the object or aircraft in question, additional information, such as the location, time of day, and any other distinguishing features, would be helpful. In cases where unusual sightings are observed, reporting them to local aviation or authorities can provide further investigation and clarification.
