Some excitement was caused on Saturday afternoon last, when a Naval balloon with one occupant made a descent in a field at Woollett Hall Farm, North Cray. The pilot found many willing hands, and the balloon was soon packed up and taken to Bexley Station.
Unfortunately this little item does not describe the balloon. However, this rounded British observation balloon from 1908, was typical of pre-WWI observation balloons.
