Impressed with Shuttle's last uncontrolled flight (8)
I believe the answer is:
stampede
'uncontrolled flight' is the definition.
(I've seen this before)
'impressed with shuttle's last' is the wordplay.
'impressed' becomes 'stamped' (stamping is a kind of impressing).
'with' means one lot of letters go next to another.
'shuttle's last' becomes 'e' (I can't justify this - if you can you should give a lot more credence to this answer).
'stamped'+'e'='STAMPEDE'
Can you help me to learn more?
(Other definitions for stampede that I've seen before include "Sudden rush of frightened animals" , "Flight of cattle in panic" , "Rapid flight" , "Panic-stricken charge of cattle" , "Beastly charge" .)
