Ha, ha! Verey droll Roz lol. Welcome also Rossim. Peterm and Rossim solved it.
Many thanks to all who've enjoyed our wee weekly.
Here are my workings, just for completion:-
1. plane (v) = make smooth = SMOOTHEN. Flies back = S; low = MOO; (to) the point = THE + N
2. anag (ground) of ‘ ethnical bean = IN THE BALANCE = unsettled
3. behind = AFT; time = ERA; manufacture = fashion; aft + era + fashion = AFTER A FASHION = in an unsatisfactory manner.
4. (homophone = taken in) settlement = pact is ‘taken in’ but it’s really PACKED = full.
5. Corrupt = ADULTERATE. sexually explicit = ADULT; E = European (as in E number); judge (v) = RATE.
