If anyone has access to Lockheed or Northrop/Grumman software I have access to a super computer (really).

In all seriousness, personal experience and "feel" are very important. Clarence (Kelly) Johnson, could tell you from "feel" whether a design parameter was correct - from an airfoil to an engine intake duct.

Not trying to be a smart a*&. Just trying to encourage all types of input and discussion.

Best regards and good flying,
