Didn't say anything about maintaining it. It is easy to attain zero g in an
airplane. And if you start out with a steep climb, you can sustain zero g
for several seconds easily. I know because I do it all the time. My kids
love watching their soda bottles floating up in front of them.

Why?

It's hard to maintain a downward acceleration of 1 G in any aircraft,
especially a small, non-aerobatic aircraft.
