1. [ Description of this aircraft ]

It is off-the-beaten-path that development and the examination of the D-21 scout drone were done in a series of blackbird program. 
It was A-12 of the U.S. Air Force becoming the launching platform of the drone. 
Two airframe(serial number 60-6940 and 60-6941) was given the repair that is necessary for this duty , and it came to be called M-21. 
The airframe of D-21 was made of titanium, and had the ability to the cruising speed was Mach 3.3, the cruising range was 2,315km,  rise up to 27,432m 
D-21 was supposed to do the operational flight by a complete automatic operation. 
The flight of the combination of the M-21 mother machine and the D-21 drone that was called "Mother and daughter" was advanced up to an important stage of separating D-21. 
However, this plan was canceled because it had suffered a large number of casualties at the same time as losing the airframe due to the accident when the separation was examined. 
Moreover, though the experiment of the D-21 drone was continued afterwards, everything was discontinued along with the disposition of SR-71.

6. [ About the directions point in FS2004 ]

This aircraft model is made by using FSDS Ver2.24. 
Therefore, it is possible to play basically in FS2004(FS9). 
However........!!
For a wide large-scale aircraft, the distortion is caused and the phenomenon of the aerofoil tip's disappearing happens in the spot shooting mode. 
If this phenomenon happens, Please switch to the spot shooting mode by using other small aircraft. 
Afterwards, if this aircraft is selected, it is normally displayed.
