Plane top in Germany, though many lost (6)
I believe the answer is:
glider
'plane' is the definition.
(glider is a type of plane)
'top in germany though many lost' is the wordplay.
I cannot quite understand how this works, but
'top' could be 'lid' (lid is a kind of top) and 'lid' is found in the answer.
'germany' could be 'ger' (I've seen this in other clues) and 'ger' is present in the remaining letters.
This accounts for all the letters.
This may be the basis of the clue (or it may be nonsense).
(Other definitions for glider that I've seen before include "Aircraft supported solely by air" , "Aircraft designed to fly without an engine" , "Unpowered aircraft" , "Powerless aircraft" , "craft without power" .)
