Where brothers famously given lift, a couple of predators (5,4)
I believe the answer is:
kitty hawk
'where brothers famously given lift' is the definition.
The definition suggests a singular noun which matches the answer.
'a couple of predators' is the wordplay.
'a couple of predators' can mean two substitutions for 'predator'.
'predator' becomes 'kitty' (I am not sure about this - if you are sure you should believe this answer much more).
'predator' becomes 'hawk' (hawk is a kind of predator).
'kitty'+'hawk'='KITTY HAWK'
Can you help me to learn more?
(Another definition for kitty hawk that I've seen is " Where you could have seen first-time flier".)
