A pilot took liberty with his flight pattern Thursday and left behind a giant penis in the sky over Okanogan County, Washington.

The Navy issued an apology after several tweets and videos showing the phallic design went viral.

"The Navy holds its aircrew to the highest standards, and we find this absolutely unacceptable, of zero training value and we are holding the crew accountable,” Navy officials told KREM 2 news.

The Federal Aviation Administration confirmed that the pilot isn’t violating any of its rules because the act didn’t pose a safety risk.
