Flights to and from London Heathrow airport are being canceled in order to silence the capital’s skies at crucial times during the Queen’s state burial.

On a typical day, aircraft approach Heathrow just to the south of Westminster, causing considerable noise.

As a sign of respect for the solemnity of this tragic and unique occasion, airport operations will be modified to prevent noise disturbances during the state funeral, the airport informs passengers.

The key times as stated by Heathrow are:

• 11.40am-12.10pm: no aircraft movements to support the two-minute silence at the conclusion of Her Majesty’s funeral.
• 1.45pm-2.20pm: no arrivals to support the procession of Her Majesty’s hearse.
• 3.05pm-4.45pm: no departures to support the ceremonial procession via the Long Walk to Windsor Castle.
• 4.45pm-9pm: a reduced departure rate to support the committal service at St George’s Chapel.
