No, I never tried to exceed mission paramaters. For some reason, the Jericho inexplicably self-destructed a number of times I tried it...and then when I went back and tried it again...it didn't...quite odd indeed. (almost as odd as my suddenly being violently disabled near the end of the mission!)
Anywho, I have completed the mission, and moved well along. Thanks for the help anyway, I appreciate it!
