The dashed line is the flight's filed/planned route and is shown when we have that data available. That's the Wall to keep out the white-walkers. The dashed blue line is the intended flight plan route. The green line is where it actually went as tracked by reception of the ADS-B transmissions from the aircraft.
Why do military planes not show up on flight radar? The main reason is that they want to protect their security and avoid detection by potential enemies. Military planes often fly on classified missions or sensitive areas that require stealth and secrecy.
On the map a coloured line shows the route of the aircraft. Purple colours indicate cruising altitudes.White colours indicate the plane is on the ground. As a plane takes off, the colours change from white, to yellow, to green, to light blue, to dark blue and finally to purple.

A note about Estimated coverage: when you see a dashed or gray line behind an aircraft, that's estimated coverage. Colored lines indicate actual positions. When an aircraft is out of coverage, we estimate based on great circle routes to destination.
The first emergency code that you may have become familiar with is Squawk 7500. This code is used to indicate that the aircraft has been hijacked, and therefore requires urgent emergency support from both security services and air traffic control.

A flight may not be visible on Flightradar24 for different reasons, but most likely it is either outside our coverage in that area or not equipped with a compatible transponder or a combination of the two.
For flights that are no longer in our coverage area, we may estimate their position for up to 240 minutes. These flight tracks are shown as black dashed lines. Read more about estimated positions on Flightradar24.
According to FlightAware, the FAA does not make flight data from military aircraft — including Air Force One — available to public websites and will block the ability to track any aircraft after a verified request from the plane's owner.
Flightradar24 has a rapidly growing network of 35,000 ground stations around the world to receive this data that then shows up as aircraft moving on a map in the app.
