Get a view of grasslands, say? Not from these (9)

I believe the answer is:

seaplanes

'view of grasslands say? not from these' is the definition.
The definition suggests an adverb but the answer is not.

'get a' is the wordplay.
I cannot quite understand how this works, but
'a' could be 'an' and 'an' is located in the answer.
This explanation may well be incorrect...

(Another definition for seaplanes that I've seen is " aircraft".)

I've seen this clue in The Independent.
