Claim 12:
13. A blast resistant shelter, comprising:
first and second structural members;
a third structural member coupled to, and extending between, the first and second structural members;
an airway defined adjacent the third structural member and between the first and second structural members;
a first blast panel mounted to the third structural member; and
a second blast panel;
wherein the first blast panel is nonrigid and frameless;
wherein the first blast panel, and the mounting of the first blast panel to the third structural member, are configured so that:
the first blast panel is permitted to flap open in response to a blast wave; and
the first blast panel remains mounted to the third structural member as the first blast panel flaps open in response to the blast wave;

wherein in a first operational configuration, the first blast panel is detachably connected to another portion of the blast resistant shelter and inhibited from flapping open so that the first blast panel prevents, or at least reduces, air flow through the airway;
wherein in a second operational configuration, in response to the blast wave, the first blast panel is detached from the another portion of the blast resistant shelter and permitted to flap open so that air flow is permitted through the airway; and
wherein the another portion of the blast resistant shelter comprises the second blast panel.
