+ * data.
+ *
+ * For each flight, the first packet
+ * is FLIGHT packet, indicating the serial number of the
+ * device and a unique number marking the number of flights
+ * recorded by this device.
+ *
+ * During flight, data from the accelerometer and barometer
+ * are recorded in SENSOR packets, using the raw 16-bit values
+ * read from the A/D converter.
+ *
+ * Also during flight, but at a lower rate, the deployment
+ * sensors are recorded in DEPLOY packets. The goal here is to
+ * detect failure in the deployment circuits.
+ *
+ * STATE packets hold state transitions as the flight computer
+ * transitions through different stages of the flight.
