Aeronef
Numerically it would be hard to say whether aeronefs or dirigibles are the more common means of taking to the air, but dirigibles have been around for a long time, and it's clear that the aeronef is ever more popular. Dirigibles have some advantages - a large dirigible is simpler to maintain and can lift more than the largest aeronef - but aeronefs are quicker and less subject to whims of weather.
Structurally, aeronefs are flat, stable platforms lifted by electrostatic levitation under the control of Lovelace stablilisers. Through appropriate linkages, the steam engines provide forward propulsive power, motivate the stabilisers and drive turbines that charge the electrostatic repulsors. The crack of discharge on landing is gradually becoming as familiar as the cry of street sellers.
Aeronefs are usually named, and like ships they have a prefix. British civilian aeronefs have the prefix SA (Steam Aeronef), while the Air Navy's vessels are prefixed with HMA (His Majesty's Aeronef).
