possible. But the damage could have been done during a radical maneuver to try to avoid collision. Would seem to me that the tanker would have been heading toward Singapore or headed to the North East away from Singapore. McCain was headed toward Singapore. If that was the case and the tanker was also headed for Singapore then they would have been on roughly parallel courses and possible an overtaking situation at the time of collision. If the tanker was headed away from Singapore, then they may have been on reciprocal courses and it could have been a meeting situation.
Hopefully, we will find out.
