Debris seen after plane brought down? (7)
I believe the answer is:
sawdust
'debris' is the definition.
(thesaurus)
'seen after plane brought down?' is the wordplay.
I cannot quite understand how this works, but
'seen' could be 'saw' (seeing is a kind of seeing) and 'saw' is located in the answer.
'down?' could be 'd' and 'd' is present in the answer.
This explanation may well be incorrect...
Can you help me to learn more?
(Other definitions for sawdust that I've seen before include "Carpenters' output" , "[WASTE] from timberyard" , "Powdery fragments of wood" , "Powdery residue from cut wood" , "Wood powder left after cutting" .)
