Top eastern state bounded by waterway where craft launched (4,9)
I believe the answer is:
cape canaveral
'where craft launched' is the definition.
(launch site of many US spacecraft)
'top eastern state bounded by waterway' is the wordplay.
I cannot really understand how this works, but
'top' could be 'cap' (cap is a kind of top) and 'cap' is located in the answer.
'eastern' could be 'e' and 'e' is located in the answer.
'state' could be 'aver' (I've seen this before) and 'aver' is present in the answer.
'waterway' could be 'canal' (I've seen this before) and 'canal' is found within the remaining letters.
This accounts for all the letters.
This may be the basis of clue (or it may be nonsense).
Can you help me to learn more?
(Other definitions for cape canaveral that I've seen before include "space reached from here" , "US space launch site" , "Florida space flight centre" , "US space launch centre" .)
