Dark scheme to eventually explode aircraft (3,5)

I believe the answer is:

jet plane

I'm a little stuck... Click here to teach me more about this clue!

'aircraft' is the definition.
(jet plane is a kind of aircraft)

'dark scheme to eventually explode' is the wordplay.
'dark' becomes 'jet' (I can't explain this - if you can you should give a lot more credence to this answer).
'scheme' becomes 'plan' (I've seen this before).
'to eventually' says to take the final letters.
The last letter of 'explode' is 'e'.
'jet'+'plan'+'e'='JET PLANE'

Can you help me to learn more?

(Other definitions for jet plane that I've seen before include "craft" , "Modern airliner" .)
