Document:
The data contained in columns marked – No, date, LA, Time, Place, Map Reference, Crater and Remarks – in this table is our transcription of the September 1944 data in AIR 20/4126 at The National Archives.
For column headed “1” of the 1,119 incidents logged in AIR 20/4126 – 366 of the incidents have been hand annotated with the letter “N”, 250 with the letter “K”, 66 with “?”, 19 with “Kew Failed”, 26 with “Dud Lighting” and 392 with no annotation at all. Therefore in this column we have included the corresponding letter, question mark or left blank – for “Kew Failed we have put “KF” and “DL” for “Dud lighting”. If anybody has any idea what these annotations represent we would be very grateful if they could share that information with us.

The deaths occurred in Bounds Green (which is part of Enfield/Southgate).
Please consider putting the street address in your excellent list. I visited the streets today.
The location given seems unlikely as there are no marks on the ground,however in the field at the end of Farm lane there appears to be a crater which looks more promising.
Firstly which actual incident are you referring to?
Secondly as stated at the top of the page all plots are located using the co-ordinates listed in the official documents. These co-ordinates are then converted as explained on the “Map References Explained” page.
Therefore the quoted co-ordinates are only as accurate as the person who recorded them and the actual map they used allowed (no GPS in those days), we believe that it is important that the “official” plot is recorded and that any further information that anybody has or finds regarding any incident is also recorded. We have heard from actual witnesses to incidents where the official records record that the rocket impacted at house number x and the witness states that it actually struck house number y.
A little official inaccuracy is hardly surprising – Don’tcha know there was a war on ?
