ii. An aircraft penetrated airspace that was delegated to another position of operation or another facility without prior coordination and approval.
iii. An aircraft penetrated airspace that was delegated to another position of operation of another facility at an altitude or route contrary to the altitude or route requested and approved in direct coordination or as specified in a Letter of Agreement, precoordination, or internal procedure.
