Recent research from the Met Office revealed that helicopters can cause an isolated lightning strike.
While flying, the helicopter acquires a negative charge, so if it flies close to an area that is positively charged (e.g. hail or a positively charged part of a cumulonimbus cloud) it can trigger a lightning strike.
If there’s a common word that describes the hotels of the Greek islands, it’s 'epic'. The stereotype of a Greek island guest room is practically legendary: whitewashed walls, cave-like forms, and impossible views from cliffs overhanging the sea. It’s one of the better formulas you’ll find anywhere and, like the sirens of Greek mythology, it’s an irresistible scene that has attracted travelers for decades.
