The attached appears to be a summary of the official accident report, note misspelling of Bovingdon.
This accident occurred in an area of The Chiltern Hills between Great and Little Missenden where the land rises from the Misbourne Valley to a height of between 500 and 600 feet amsl. There is no indication of time but perhaps one could guess that the crash happened in the evening. Note the traces of snow.
