Weekly Challenge #36: Rover Race
No levels for this one; just share your best time! Rules:
Start at Runway R's south taxiway's crosswalk and race around the entire runway, back to the crosswalk (see map).
Your vehicle may use any propulsion method, including detachable boosters or other expendable parts...
But your active, kerbal-piloted vessel must not leave the ground.
Your vehicle must not leave the pavement or touch grass.
