Having read through this now almost 30 years later, I can see that there are quite a few points that are missing from this list. A quick search on Google for 'Flying tops' led me to this very useful site: www.fabflour.co.uk/fab-baking/what-went-wrong/what-went-wrong-bread/ from The Flour Advisory Board which gives some other reasons for faults in bread and answers the mystery of the 'Flying Top', of course, now its obvious!
