I did a dig on this that made notables but I cannot remember what bread. In regards to Q #231 I cracked T: B, F, J, 1, 5, 11-20 ^ to be T: 24 - 11 - 20.
Also, SAT_40K_se_c_[30m] translates to Satellite_40km_South East_Castle_[30m]
Joint Andrews Airforce Base is South East of the White House. I know there are communications there to do with satellites and stuff.
Joint Andrews falls within a 40km radius of the White House. That is what drew me to the conclusion.
