Doesn't the various secretaries & the VP need choppers??Not to mention the first lady.I think of the 23,around 4 will probably be exclusively for the President & be fitted with state of the art communications,jammers & countermeasures-the rest being relatively downgraded variants.
The secretaries do not need helicopters. The VP might need one.
Not to mention the first lady.
She does not need a presidential helicopter. She occupies no office of government. She does not get paid. She has no official duties.
There's no way we need 23 presidential helicopters.
