Did low-flying Buccaneers cause disputes in exercises?

Did ships in allied exercises reject Buccaneer hits because the aircraft approached too low and fast to be seen?

Yes, disputes are recalled, including an uncertain account of crews using squashy loads to prove that their delivery angle could hit a ship.

American objections that Buccaneers were cheating are recalled in connection with their very low attack profiles. Conventional bombing involved a fast, low approach at about Mach 0.9, followed by a sharp pull-up to release the bombs and clear the target. One anecdote is tentatively attributed to Michael Clapp: after an earlier exercise disputed whether that delivery angle could work, crews dropped squashy loads onto the opposing ships. The precise contents and whether the opponents were American or French are uncertain in the recollection. The messy impact was intended to settle the dispute with visible evidence.
