St Elmos
We used to get St Elmos fire on the twin ADF Ae on the nose of the Hastings. That and the ADF unlocking and trying to find the nearest cu nim were usually the only signs that we were anywhere near trouble. No 'cloud and clonk ' in that venerable frame. Also had several strikes in the Herc. Worst was en route Kiev to Lyneham, big bang, flash and a slowish ball of lightning rolling down the cargo compt. Followed by a loud banging on the fuselage roof a la Tony Hancock. One of the Hf Ae had come adrift and frightened us to death. We diverted to Brno where the G/E removed it and we carried on to Lyneham. I believe the exit hole for the strike was up in the 'ducksbill but it seems a long time ago now so I could be wrong. And no the E290 had not given any indication of trouble.
