Going to Malta around 1966 in a BEA Trident 3B I needed the loo in the cruise and was just squeezing past the Steward (face to face) because he had his trolley in the aisle when there was the mother and father of all bangs as we were hit by lightning. The expression of sheer terror on his face was something to behold from only a few inches away. As it happened I had been hit by lightning the day before in a Meteor doing thunderstorm penetration trials for RAE Bedford (and we know how currency helps in aviation) so I just gave him a smile and said in his port ear "Don't worry mate it's only lightning". The look of relief and gratitude that followed suggested to me that I could have been on a promise in Malta if I had so wished.
