NECKAR HIGHWAY in passage on a south-westerly course at a speed of 16 knots. ORION was
situated close to NECKAR HIGHWAY's expected track at one minute’s distance. Though it appears
that ORION was situated just outside NECKAR HIGHWAY's heading, the actual size of NECKAR
HIGHWAY means that ORION was in fact drifting at a maximum of a few metres' distance from
NECKAR HIGHWAY’s expected track.
