Data sources & notes
Data source: public ADS-B data
All positions come from publicly broadcast ADS-B signals that every aircraft transmits unencrypted and that volunteers around the world receive. Data may be delayed, incomplete or inaccurate.
Linking an aircraft to a well-known person is based on public sources such as media reports and registry data. "Jet attributed to X" explicitly does not mean that this person is on board or ordered the flight — aircraft are also chartered, sold or used by others.
All information is provided without warranty; no liability is accepted for accuracy or completeness. CO₂ figures are estimates based on typical fuel burn for the aircraft class.
Using this data to harass, track or stalk people is prohibited.
