• at least one retaining strap, wherein a first end region of the at least one retaining strap is coupled to the aerial vehicle, and wherein a second end region of the at least one retaining strap is coupled to a release mechanism;
• and
• the release mechanism, wherein the distal end region of each securement strap of the plurality of securement straps is coupled to the release mechanism, wherein the delivery system is configured such that when the release mechanism is actuated the release mechanism releases the distal end region of at least one securement strap of the plurality of securement straps, thereby delivering the package, and wherein the release mechanism is configured to remain coupled to the second end region of the at least one retaining strap when the release mechanism is actuated.
