Okay, so it's rendering every aircraft as if it is at max reflectivity. Probably not a problem with the aircraft models, or dds files.
The next most likely candidate is your shaders.xml file since it would effect every airplane the same.
Check to see if you have a section near the top that looks like this:
ModelSpecularGloss Desc="Vertex lighting w/ Specular modulated by Gloss map"
Lighting="True" SpecularEnable="True"
SrcBlend="One" DestBlend="Zero"
ZEnable="True" ZFunc="[ZFunc]" ZWriteEnable="True" ZBias="0" FogEnable="True"
AlphaBlendEnable="true" AlphaTestEnable="true" AlphaRef="8" MultiSample="True"
ColorArg10="Texture" ColorOp0="Modulate" ColorArg20="Diffuse"
AlphaArg10="Texture" AlphaOp0="SelectArg1" AlphaArg20="Current"
Texture0="0"
ColorArg01="Current" ColorArg11="Specular" ColorOp1="MultiplyAdd" ColorArg21="Texture"
AlphaArg11="Current" AlphaOp1="Modulate" AlphaArg21="TFactor"
Texture1="3" TexCoordIndex="0"
