A passive guidance mechanism enables smooth guiding to a desired position; and a flying object landing system enables smooth guiding to and landing at a desired position. A pair of guide rails are arranged side by side with a space therebetween, and are provided so that the space increases toward one set of tips of the guide rails. One guide rail is supported so as to be rotatable about a first shaft extending in a direction perpendicular to a plane including the guide rails, at or near the tip of the guide rail. The other guide rail is supported so as to be rotatable about a second shaft extending in a direction perpendicular to the plane including the guide rails, at or near the tip of the guide rail.

Landing pads for a drone. One of the landing pads can include a landing area with a first surface configured to receive a second surface of a landing gear of a drone; a docking area i) with a first end adjacent to the landing area and a second opposite end and ii) a docking surface configured to contact the second surface of the landing gear of the drone; a fixed member i) with a third surface adjacent to the second end of the docking area and ii) configured to contact an end of the landing gear of the drone; a moveable member configured to i) move the landing gear across the first surface of the landing area onto the docking surface and ii) secure the landing gear of the drone in place between the docking surface of the docking area and the third surface of the fixed member.

A drone docking structure of an autonomous vehicle can include: a coil housing having a space for docking a drone to the vehicle; a docking cover configured to open or close a top portion of the coil housing according to whether the drone is docked; and a motor housing installed on a side surface of the coil housing and including a motor configured to actuate the docking cover.

A tie-down for attachment to an aft tail section of an aircraft for inhibiting damage to the aircraft when the aircraft is on the ground is disclosed. The tie-down has a mount member configured to attach to the aft tail section and a projection member supported by the mount member. The projection member extends in a generally downward direction from the mount member so as to provide a contact surface with the ground that is lower than the aft tail section.
