An attachment mechanism includes a compliance member positioned between a body and bayonets. The bayonets collectively define an aperture therebetween. Alignment members prevent rotation of the bayonets relative to the body while allowing the bayonets to move radially outwardly against the compliance member. When a second attachment mechanism is received in the aperture of the first attachment mechanism, relative rotation therebetween may interlock corresponding bayonets thereof. The attachment mechanisms may release from one another in a drop event or other incidence of force applied thereto by allowing a bayonet to radially move outwardly out of contact with a corresponding bayonet of the second attachment mechanism.
