"I mean, I think they've been curtailed with [flying in a helicopter] a little bit," Palmer told the Express. "I think the Queen felt, certainty let it be known, that she felt uncomfortable about the entire family traveling by helicopter."
Per a royal rule, royals shouldn't travel together in case an accident happens and the lineage is destroyed. "For whatever reason, the Queen let it be known that she was worried about the Cambridges traveling as a family by helicopter because of the possibility of a crash," Palmer noted.
Since William and Kate Middleton's children, Prince George, 8, Princess Charlotte, 7, and Prince Louis, 4, are all third, fourth and fifth in line to the throne, it would not be a good situation for the pair to be in.
"I think there was partly a bit more going on behind the scenes," Palmer said. "I think there was a little bit of official unhappiness about the amount of time that the Cambridges were spending traveling between Anmer Hall in Norfolk and Kensington Palace, their London residence, using helicopters. People in the Cambridges' camp would say actually that didn't happen very often at all. Other people seemed to imply that it was happening a bit more than the Queen wanted it to happen."
This is hardly the first time the 96-year-old matriarch has put up a fight against William riding in a chopper, despite him being a trained helicopter pilot.
"Her Majesty has told close friends and courtiers that she would like William to stop flying himself, particularly in bad weather, as helicopters are not the safest form of transport. It keeps the Queen awake at night and she is understandably very worried," a source told The Sun in 2021.
