I think the reason the armory dance at Ft Dix wasn’t bombed was because the bomb makers had a “work accident” at a house during assmbly- the same one that led to Ayers adopting the bomber’s kids with the Russian names.
6 March 1970 bomb factory located in New Yorks Greenwich Village accidentally explodes. WUO members die, including Ayers girlfriend, Diana Oughton. The bomb was intended to be planted at a non-commissioned officers dance at Fort Dix, New Jersey. The bomb was packed with nails TO INFILICT MAXIMUM CASUALTIES UPON DETONATION.
