The SNCO ic Fire Section at a station I was based at, placed regular demands for the 'bone and blood' foam. The stuff would arrive and be issued to said section. In fact, we had a pretty good turnover of the stuff. Whilst we didn't have any aircraft, what we did have was a very nice walled garden which belonged to the manor house after which the station was named. In the walled garden were some very large greenhouses in which large crops of tomatoes and other veg were grown(SNCO ic Fire Section was also SNCO ic Station Garden). Some "manager" at Harrogate queried one of our demands and asked what aircraft type we operated... then stopped further issues as the stuff was "for use by flying stations only".
