e = tree finally

[bobbinwales]

ladies yes, something like anagram of idaleaps minus a P?

[bwiltshi]

Concorde = agreement from plane concord + e (tree finally)

[Bluesdayschild]

bobbinwales is correct - the answer is: Concorde: Concord (as in agreement) & 'E' the last letter of tree to give you the 'Concorde' as in the supersonic plane.
