A method and system (1) for propagating data such as entertainment data in an airline system (1) is disclosed. The entertainment data may comprise video, audio and games data. A computer server device (3) is provided at an airline terminal, and a mobile computer (13) is provided in an aircraft (11) with a hard disk array for storage of the digital data. The data can be propagated in the system (1) to aircraft (11) and to further airline terminals by an automatic software function which occurs when an aircraft mobile computer (13) electrically connects with the server computer (3) at the terminal. Such connection is made between the aircraft (11) and an aerobridge (9) at the airline terminal. The software provides checking to see if the mobile computer (13) is an authorised computer, and also to determine whether the data in the mobile computer (13) is more recent than the data in the computer server (3) or vice versa and then a data exchange occurs to replace the old data with new data. As further aircraft (11) visit the airline terminal their data is updated and the data is therefor propagated in the system (1). Devices (21) are also provided on each side of the connection between the aircraft (11) and the airline terminal for initiating security checking and for providing data pass through capability. Each mobile computer (13) has a personality module (57) which configures the computer (13) to the environment in which it is placed. Thus, identical computers (13) can be used in an airline system which may have different types of aircraft. The personality module (57) configures the computer (13) to the particular aircraft.
