hi all. i just killed dr.no and i should be escaping in his air craft but i went out of an opening and im stuck on this like round big black thing and i cant walk i can shoot and turn but wont walk should this happen .

You must have fallen down the hole by the ladder
just turn around until you see a ladder then climb up it then right back down.
go through the bulkhead that opens then walk into the plane to end the mission.
that is if you have killed dr no
