Explanation:

People often confuse the terms used for certain types of attack, and most commonly use the term blitzkrieg for any type of sudden, quick attack, be it by air force or on the ground. This is not true. The term blitz is almost never used, though that is actually the correct term for what is often referred to as blitzkrieg, the sudden, quick attacks by the air forces. The blitz represents strictly and air attack, without any warning, out of nowhere, and with high efficiency in most cases. This types of attacks have happened in numerous occasions, and one example of it is the German attack on Britain. The Germans did not saw it practical to engage into a war in the ground, so they only used the air force to attack the island nation and cause damage to it.
