optionally, instructor data containing a name and password;

optionally, operator data containing a name and password; and

the access permission scheme based on the user data such that;

an operator using the computing unit'"'"'s user interface software is granted access only to logs that carry that operator'"'"'s data, providing the operator has provided the proper password to the user interface;

an instructor using the computing unit'"'"'s user interface software is granted access only to logs that carry that instructor'"'"'s data, either as instructor or operator, providing the instructor has provided the proper password to the user interface; and

an owner using the computing unit'"'"'s user interface software is granted access to all logs, providing the owner has provided the proper password to the user interface.

8. The motion dynamics recorder of claim 1, further comprising a port for connecting to an audio and/or visual display device, wherein the motion dynamics recorder is configured to output at least some of the data to the audio and/or visual display device in real-time.

9. The motion dynamics recorder of claim 1, wherein the motion dynamics recorder is configured to stream the data to an external device while the motion dynamics recorder is performing one or more of the following operations:

measuring motion, generating data, and writing data to the memory module.

10. The motion dynamics recorder of claim 9, further configured to stream data to the external device while the motion dynamics recorder measures and generates data;

wherein the motion dynamics recorder streams data to the external device, with or without the local memory module inserted into the slot; and

wherein motion dynamics recorder streams data to the external device, with or without the remote memory module in communication with the recorder.

11. The motion dynamics recorder of claim 1, wherein the motion dynamics recorder is configured to operate within a vehicle comprising a switched power bus and an unswitched power bus, and the motion dynamics recorder further comprises two power sources, the two power sources comprising:

a switched power input connectable to the vehicle'"'"'s switched power bus; and

a backup power input connectable to a charge storage device connected to the vehicle'"'"'s unswitched power bus;

wherein the motion dynamics recorder is configured to draw power from the backup input when power from the switched power input is turned off while the motion dynamics recorder has open logs receiving data.

12. The motion dynamics recorder of claim 11, wherein the motion dynamics recorder is configured to automatically shut down when the vehicle main power is off, except the motion dynamics recorder is configured to remain on and draw power from the backup power input if the motion dynamics recorder is in the process of writing data to open logs on one or more memory modules and to shut off the backup power and shut down the motion dynamics recorder when the motion dynamics recorder closes the last open log.

13. The motion dynamics recorder of claim 1, wherein the motion dynamics recorder is configured to generate motion tracking data, the sensor array of the motion dynamics recorder further comprising:

an inertial tracking module for tracking the vehicle'"'"'s motion using the laws of inertia; and

a satellite based tracking module for tracking the vehicle'"'"'s motion using a satellite positioning system.

14. The motion dynamics recorder of claim 13, wherein the tracking data comprises:
