Two Marine Corps pilots have been grounded amid an investigation into allegations they drew a giant penis with their flight path over Southern California last month.

The Corps opened an investigation after the military-grade sky dong was made by a T-34C trainer aircraft from Marine Fighter Attack Training Squadron 101 out of Miramar, California. The phallic image was first spotted just west of an aerial gunnery range by a Twitter user known for surfacing interesting flights:

“The T-34C crew that are being investigated for flying a pattern resembling an obscene image are currently not flying pending the results of an ongoing investigation,” Maj. Josef Patterson, a spokesman for 3rd Marine Aircraft, told The Washington Examiner.

“Although not flying for the time-being, the two Marine Corps aviators are still providing vital squadron ground support functions.”
