Is that a drone or a plane? Experts help explain the differences

Mysterious nighttime flights, initially spotted near military facilities and Trump's golf course, have sparked concern. Experts say distinguishing drones from other aircraft at night can be challenging. While drones typically have a single anti-collision light, some have multiple lights, making distance and size estimation difficult. Their quieter, high-pitched buzzing noise and agile movements can be clues, but not definitive identifiers.
