The Princess of Wales was all giggles when a lifejacket she was wearing suddenly inflated during a visit to a Royal Navy air base. Kate erupted in laughter as she was being shown around Royal Naval Air Station (RNAS) Yeovilton in Somerset. During the visit, the princess also spent time in the air traffic control tower and spoke over the radio with the crew of a Wildcat helicopter as it came in to land. Report by Blairm.
