Sorry to be pedantic Rakshasa but there is not one mention of Constance Babbington-Smith in the recent BBC 'OPERATION CROSSBOW" Documentary.
In all the 59:02 minutes - not one hint of Constance B-S. Dr R.V. Jones
Plenty of footage in the 1988 "Secret War" Episode 3, along with the amazing R.V.Jones.
BTW Peenemünde was already known about from the 'Oslo Report' in 1939! Not some
PR pilot with some spare emulsion available.
RV Jones Chapter 38 MOST SECRET WAR page 332 paperback edition
The 1988 BBC "Secret War" Ep 3 was so much better researched IMHO.
