I remember a story about a pilot being informed by a tower he had committed a "225-able offence". Superstitions associated with the numbers 225 still dilate the pupils a bit for older folk. No way would I give a heading of 225, 230 will do the same job...
For these reasons the Incident Report form ended it's days as form number CA2593, but this change happened about 1987. This makes Keg's decade a bit suss, unless the center's form cupboard was a historical midden.
