Guy Lambton Menzies (20 August 1909 – 1 November 1940) was an Australian aviator who flew the first solo trans-Tasman flight, from Sydney, Australia to the West Coast of New Zealand, on 7 January 1931.

They deemed the youngster westward-bound; He scarce was out of sight Before the ’wildered watchers found He wouldn’t overland around The Great Australian Bight.

The moon at Mascot, round and rich, Beams on him, rising from the pitch, And ere the sun is low He’s safe at Harihari, which Is close to Herepo.

[6] His younger brother, Ian Lambton Menzies (1912–1941), who served in the RAAF, died on 18 April 1941 in an aircraft accident near Ravenswood, Queensland, and about 100 km miles south of Townsville.

[16][17] The fact that the Sydney press announcement of his impending marriage identified his future wife as one "Mrs. Marcia Ina Grundy" is highly significant.

[32] While still a teenager, Menzies was a well-performed dirt-track, concrete track, and speedway motorcycle rider who raced under the assumed name of Don McKay, and was billed as "The Flying Scotchman".

[33][34] A number of other Australian speedway riders, such as Dave Brewster, Ern Buck, Vic Huxley, Bill Kilminster, Charlie Spinks, and Lionel Van Praag also held pilot's licenses.

An extensive outdoor historical marker with photographs and descriptions is located at GPS coordinates −43.076716, 170.531477 (south latitude, east longitude).

[50][51] He and his crew were killed on 1 November 1940, when his Short Sunderland flying boat (N9020) was shot down over the Mediterranean Sea while en route from Malta to Sicily.
