Navy officials are failing to see the funny side of the efforts of a mischievous pilot who drew enormous penises in the sky above Washington this week.

The unnamed pilot from Naval Air Station Whidbey Island, was lambasted by officials who have since apologized for the obscene display in Okanogan.

'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,' they said in a statement.

They described the act as 'immature' and 'unethical' and said that action was being taken to punish the crew responsible.

While they failed to see the humorous side, the internet exploded with appreciation for the pilot's drawings.
