All Meghan Markle could hear was the cheering crowd.

Airplanes were prevented from flying over Windsor Castle for 15 minutes as the arrived at St. George’s Chapel, the UK’s National Air Traffic Services (NATS) said.

In a statement, a NATS spokesman said “Heathrow Airport has agreed to provide a 15 minute no-fly period over Windsor on the day of the royal wedding on 19 May.”

Passengers were assured there wouldn’t be any disruption at one of the world’s busiest airports, just east of the castle.

Windsor is underneath one of the main four flight paths for Heathrow and planes are often seen, and heard, taking off or coming in for landing near the castle on a daily basis.
