How aircraft move? Or moves?

1

I saw a book titled

"How Aircraft Move Through the Air".

But is that correct? I think aircraft is the singular. So Would it be "moves" or "moved"(in case of past sentence)?

Am I wrong? Please let me know. Thanks.

Aircraft is both singular and plural. Like sheep.

If it is used in a way that could be singular or plural, the singular is denoted by use of an article.

"How aircraft move through the air"

Plural.

"How an aircraft moves through the air"

Singular.

A definite article can be applied to the singular or plural (the plural potentially acting more like a mass noun).

"How the aircraft moves through the air"

"How the aircraft move through the air"

Both are valid, but with different meaning.
