In the print edition of today's G & M it states the bomb  "...was one of thousands dropped over Germany by the Royal Air Force...to cripple the Nazi war machine and demoralize the German population." neither of which objective was achieved by "terror" bombing Germany's cities. The actual objective of the R.A.F. was to kill and "de-house" the civilian population. The bombing effects on the dispersed war production and on German morale was negligible. The R.A.F. resorted to bombing cities because they simply could not find or hit industrial targets.
