    Eagle is heading down faster than anticipated... P63 is a program that fires the descent engine based upon ALL data concerning positioning of the LM after it left the CM. P63 needs the IMU data to know how to calculate and steer the LM to the selected landing area. The reason cited for Eagle going "long" downrange is excess pressure in the tunnel between the CM and the LM. As I said above... Why doesn't P63 recognize that the LM is moving down too rapidly from the 'get go?" The LM IMU only had ONE job to do: keep track of Inertial Movement to feed accurate data to P63. Did it not detect the "pop" and acceleration? Instead, P63 starts as if everything for the recent 45 minutes is based upon perfect IMU calculations. Why have the IMU, or P63 if the don't/can't update based upon real time data?
