Not a soul has kept dry in front of aircraft (4,4)
I believe the answer is:
nose cone
'front of aircraft' is the definition.
'nose cone' can be an answer for 'front' (nose cone is a kind of front). I am not sure about the 'of aircraft' bit.
'not a soul has kept dry' is the wordplay.
'not a soul' becomes 'none' (both can mean nobody).
'has' is an insertion indicator.
'kept dry' becomes 'seco' (I've seen this before. I am not sure about the 'kept' bit.).
'none' going around 'seco' is 'NOSE-CONE'.
'in' is the link.
Can you help me to learn more?
(Other definitions for nose cone that I've seen before include "Front of rocket" , "Front section of spacecraft" , "Part of aircraft" , "Head of Enterprise perhaps" , "Pointed front of missile" .)
