Airplanes were not introduced in WW1, their use predates the war. Many countries had fledling air corps years before WW1. Aircraft were used for bombing missions as early as Aug of 1914.
Tanks, however, were new.
In 1939, The World War II itself began.

The first fatal airplane crash occurred in September of 1908 and was flying at about 150 feet when problems with the flight began.
The airplane began to develop with the army and with the jet flyers.
World War One began during 1914 and ended during 1918.
No war 'began when the Holocaust began'. The Holocaust took place during World War 2 but was not one of the causes of the war.
In 1939, The World War II itself began.
Both the tank and the airplane were both first used in a military context during World War I (1914-18). Aircraft combat began shortly after the war started in 1914, but didn't become a serious affair until mid-1915, when effective mountings of forward-firing machine guns enabled the creation of the first "fighter" aircraft.Likewise, the tank was first introduced at the Battle of the Somme in 1916.Thus, no war actually began with the first introduction of tanks and aircraft.Some people would claim that the concept of mechanized warfare began with introduction of the tank and aircraft. In my opinion, however, this is incorrect, for several reasons:Mechanized Warfare, while benefiting from aircraft, does not require them. Mechanized warfare is a land-based strategy.Tanks are NOT sufficient for Mechanized Warfare - a significant motorized (or mechanized) infantry capacity is also required, as is a completely motorized logistical supply chain.The tactics involved with Mechanized Warfare and the overall strategy to employ those tactics requires certain minimum technological capabilities of equipment, none of which were present during WW1.The actual theory of mobile armored warfare was not developed until after World War 1, and frankly wasn't even remotely usable in terms of practical application of available machinery and more mature tactics until the early 1930s.Thus, while having tanks is certainly a prerequisite to developing mechanized warfare strategy, it is not sufficient. And, aircraft are orthogonal to mechanized warfare.meachanized warfare
During World War I, airplane pilots transitioned into fighter roles as the need for aerial combat emerged. Initially used for reconnaissance, aircraft soon faced threats from enemy planes, prompting the development of tactics for air-to-air combat. Pilots began modifying aircraft with machine guns and other weapons, leading to the rise of dedicated fighter pilots who engaged in dogfights to gain air superiority. This evolution marked the beginning of aerial warfare as a critical component of military strategy.
The began to do this in 1943.
