The delay is not ‘caused’ by aircraft inbound to or outbound from Willy, military or otherwise.
The delay is caused by 1950s procedures that still treat an aircraft miles away from the extended centreline of the Willy runway, at 500’ AGL, as being a material risk to aircraft inbound to or outbound from Willy (military or otherwise).
Someone give me the probabilities of an aircraft inbound or outbound from Willy colliding with an aircraft at 500’ over Stockton Beach.
Hopefully someone will pipe up and say: “Even if it’s a vanishingly remote risk, it can be mitigated by making people hold over 10 nautical miles away”, thus proving the point.
