The Vulcan, VC10 and C17 Globemaster are very different looking aircraft, as most people would know. The distinctive shape of the Vulcan's delta wing is instantly recognisable, while the VC10 has its 4 engines mounted in pods of two at the rear of each side of the aircraft. The C17 has its 4 engines more conventionally mounted under the wings, and has winglets on each wing tip. The RAAF flies C17s, which occasionally make visits to nearby Ballina airport, presumably on training missions.
In my opinion they are all impressive aircraft, particularly the Vulcan which had a wing shape unique in heavy aircraft. As far as I am aware, it's the only heavy bomber with a delta wing. The VC10 was used by BOAC on its services to Australia back in the 70s, and I always admired its clean lines with the rear mounted engines. When my young sister and her English husband moved to Australia in 1974, they flew in a BOAC VC10. The C17 looks a very purposeful and rugged aircraft, and should have a long service life.
