Singaporean pilots appear to be getting a little carried away as they enjoy themselves over the skies of Western Australia on Thursday.

Keen plane spotters noticed on flight radars that a Pilatus PC-21 training aircraft appeared to be flying a route that closely resembled a penis and testicles.

Flight radars picked up the contours above Bullsbrook, 41km north of Perth, on Thursday afternoon.

The aircraft took off from RAAF Base Pearce at 12.25pm ​​and returned at 1.28pm.

Two Singaporean squadrons, the No. 130 and the No. 130 trainer, are stationed at the base.

The rough flight path was picked up on the flight tracking website Flightradar24.

Singapore signed a Memorandum of Understanding with the Australian government in 1993, which was valid for 25 years.

This document allows Singapore to conduct its RSAF pilot training program in Australia, as the city-state has a limited amount of airspace.

Daily Mail Australia has contacted the Singapore embassy for comment.
