January

January 17 - The first United States Navy airplane flight in the Hawaiian Islands takes place when a plane takes off from Honolulu.
January 21
* The last Royal Navy balloon ship, HMS Canning, which has operated since December 1916 as a balloon depot ship, is sold.
* The Royal Air Forces "Z Unit" - the first self-contained air unit dedicated to "aerial policing", the use of independent air power to suppress colonial rebellions - begins operations in British Somaliland against the Dervish State of Diiriye Guure and Mohammed Abdullah Hassan using 10 Airco DH.9s. On the first day, a DH.9 drops a bomb on the tent of the Mullah - who has never seen an airplane before and whose advisers tell him that the aircraft must be either chariots from Allah or friendly messengers from the Ottoman Empires Sultan Mehmed VI - while he waits to receive their crews as important guests. He survives and flees. The Z Unit will continue to bomb and strafe the Mullahs forces on January 22 and 23.
January 24 - Extensive aerial reconnaissance by the Royal Air Forces Z Unit establishes that the Dervish State has abandoned the area around its Dhulbahante garesa forts at Medishi and Jid Ali. Independent air operations against the forces of Diiriye Guure and Mohammed Abdullah Hassan end, and the Z Unit begins direct support to British troops pursuing Hassan.
January 29 - Royal Air Force Airco DH.9s bomb the Dervish State's Dhulbahante garesa fort at Gallbaridur.
January 30 - Royal Air Force DH.9s bomb Mohammed Abdullah Hassans baggage train and personal retinue, but he survives.

February

Alan A. Griffith's analysis of the process of brittle fracture is published.
Early in the month, Royal Air Force Airco DH.9s bomb the Dervish State stronghold at Tale, including Mohammed Abdullah Hassans personal compound. Hassan again survives and flees into Abyssinia. The British campaign to restore their control over British Somaliland comes to a successful conclusion in only three weeks, at a low cost in British lives and money. It is the prototype of the "aerial policing" of rebellious colonies that the Royal Air Force will conduct in the 1920s and 1930s, most notably in Iraq.

During the trip, they had stopped at Bari in Italy; Valona in Albania; Thessaloniki, Greece; İzmir, Aydın, and Antalya in Turkey; Aleppo, Baghdad, and Basrah in Mesopotamia; Bushehr, Bandar Abbas, and Chabar in Persia; and in rural Baluchistan, Hyderabad, at an unnamed place, and in Karachi, and Delhi in British India. At Delhi, Masiero's SVA-9 had been destroyed in a hard landing, so he and his mechanic had taken a train to Calcutta, while Ferrarin and his mechanic had flown on to Calcutta, stopping at Allahabad and flying over the Taj Mahal at Agra along the way. From Calcutta, the two pilots had switched to new SVA-9s and flown on to Rangoon in Burma; Bangkok and Ubon in Siam; Hanoi in French Indochina; Portuguese Macao; and Guangzhou and Fuzhou in China, where Masiero's SVA-9 had been destroyed in a crash. Masiero and his mechanic had then traveled to Shanghai by boat while Ferrarin flew there. At Shanghai, Masiero had taken possession of a new SVA-9 and the two pilots had flown on to Qingdao and Mukden in China; Sinuiju, Seoul, and Taegu in Chosen; and then across the Sea of Japan to a stop at Osaka, Japan, before arriving at Yoyogi Army Field in Tokyo.
* Bert Hinkler flies the first leg of an attempt to fly from England to Australia in an Avro Baby, departing London's Croydon Airport and flying to Turin, Italy, in 9 hours 30 minutes, crossing the Alps during the flight. Although mechanical problems force him to abandon his plans to continue beyond Turin, he wins the Britannia Trophy for his Croydon-Turin flight.
