Thank you for your reply.  :)

I am not requesting tutorial information on creating or editing textures - I know how to do that.  What I need is the following information specific to your CaptainSim product:

i. is this glow on the left fuselage at the tail programmed with the nav lights or is it produced by one of the texture files?
ii. if it is produced by a CaptainSim texture file, which file do I edit?
iii. if it is programmed with the nav lights, why does it appear on only the left side of the fuselage and not the right?
iv. if it is programmed with the nav lights would CaptainSim consider producing a patch to make it symmetrical on both sides of the fuselage?
v. did the real world 707 have lighting on the tail to illuminate the airline logo?

I look forward to hearing from you at your earliest convenience.

Regards,
Brian
