You knew it was only a matter of time. YouTube user "Sickest shot" posted video on Tuesday of naval aviators drawing a penis in the sky over Washington state last Thursday.

The Navy apologized Friday, a day after images were posted to social media showing the aviators flying an EA-18G Growler over Okanogan County.

In the video, which contains explicit language, people can be heard marveling at the image before they realize what it is.

"Oh my God, this is tight."

"Think how fast he's probably going."

"All gas, no brakes."

The Navy on Friday grounded the aviators, who belong to Electronic Attack Squadron 130, based on Naval Air Station Whidbey Island, Wash.

"The American people rightfully expect that those who wear the Wings of Gold exhibit a level of maturity commensurate with the missions and aircraft with which they've been entrusted," Vice Adm. Mike Shoemaker, Naval Air Forces commander, said on Friday. "Naval aviation continually strives to foster an environment of dignity and respect. Sophomoric and immature antics of a sexual nature have no place in Naval aviation today. We will investigate this incident to get all the facts and act accordingly."

A spokesperson for Naval Air Forces said Monday the investigation was still ongoing and that it would be "inappropriate to discuss any actions surrounding the investigation."

"We can provide an update once all investigations surrounding this matter are complete," Lt. Cmdr. Leslie Hubbell said. "We do not have a timeline as to when that might be."
