We have also had demonstrations of a single match behind a pillar in the body preventing a particular panel from diaphragming, and thus curing a very pronounced boom. The general outlook is to slacken everything off and make sure there are no d----- silly contacts. However, in the case of Blackmer, I think the Coach-builders should do their share.
