“H-Bomb” is a nickname given to me while I was singing in a cover band. I joked with a band member whose name began with the letter A that he was like an A-Bomb after a performance. He kindly demurred that H-Bombs are more powerful. The nickname stuck in the band.
Fast forward to working with NAVAIR PMA-208 for an event in Ventura, CA when I learned about call signs and their use. I wrote “H-Bomb” on my name tag to join in the tradition. The Program Manager — an awesome human — addressed me as H-Bomb when presenting me with a challenge coin at the end of the event and took to calling me by my call sign for the duration of the project. Something I loved so much!
