FAQ
Frequently Asked Questions
It is both. The word does not change: one aircraft, two aircraft.

Because '-craft' in this compound (like in 'spacecraft', 'watercraft') is a mass noun meaning 'vehicle' and traditionally does not take an '-s' in the plural.
Yes, absolutely. A helicopter is a type of rotorcraft, which falls under the general category of 'aircraft'.
