Enemy It is estimated that about 40 enemy aircraft operated over or near our coasts during the day of 18th October. Caistor unserviceable by day and night. A small number of enemy aircraft operating during the day dropped a few bombs in Kent, Surrey and London where damage was of a minor character and casualties low. Night activity directed against London was on a far smaller scale than recently. Liverpool and particularly Birmingham were subjected to raids, the latter receiving considerable damage.
Information is to hand of a new type of bomb which is of considerable interest.
It appears that eight HE are strung together by wire and dropped by parachute, the material of which is non-inflammable. A wire trailing behind exploding the first bomb when contact is made with an object. The explosive force from this drives the parachute up again and the procedure is repeated as each bomb explodes. Attacked at 2330 hours on the 16th. Three mushroom craters and one unexploded bomb across centre of Aerodrome.
