There were a number of odd one-off Hurricane experiments. One of the
more interesting was the "biplane" Hurricane, which featured a
jettisonable top wing with integral fuel tanks to reduce take-off
distance with heavy loads, and to improve ferry range. The wing
required the relocation of the radio mast to the belly of the
aircraft. The modification was implemented by F. Hills& Sons and was
designated the "Hillson FH.40". It proved too heavy to be serviceable.

PS Thank you for the post; I had never heard of that airplane.

I can 'see' the tail being knocked off during jettisoning the upper
'wing' too....

Just turn upside down and push ths stick?
