Aerial Earth Circumnavigation Challenge Objective: Circumnavigate Earth (not Kerbin!) by air. DISCLAMER: I'm not completely sure this can be accomplished. Rules: 1)  The only method of propulsion allowed is airbreathing engines.  No rockets, kraken drives, or other shenanigans. 2)  Only 2 points of ground contact are allowed: takeoff and landing.  This is to prevent ISRU. 3)  No drop tanks or other staging.  The craft must be single stage. 4)  Stock parts only
