As it turns out, royal experts believe that the real reason Princes William and Harry cannot fly together is because Buckingham Palace fears that, in a worst case scenario involving the death of both brothers, there would be a “constitutional crisis” to the line of succession. Royal author and constitutional expert Brian Hoey told The Sun that there is a “strong constitutional reason that William and Harry do not fly together — and that is to do with the line of succession.” Hoey said that while “events happened very quickly,” referring to the sudden and dramatic news of the queen’s ill health the morning of September 8, “They have had years to plan for all eventualities.” This, of course, includes the possibilities of tragic and deadly accidents.
If William were to die, the heir apparent to the British throne would be his son, the 9-year-old Prince George. And in that scenario, the death of King Charles III, who is 73, would result in a child becoming king. According to The Washington Post, George would technically be allowed to become king, but he would not be able to carry out official duties until he became 18. As a result, Harry — the next adult in line to the throne after William — would act as regent until George’s 18th birthday. As a result, Buckingham Palace has to constantly plan ahead in order to avoid worst-case scenarios.
