As a licensed engineer and also ex military engineer whom has exposure to AAES, I totally agree with Hebog's post. I thought guys in this country would not try and pull the same stunts as Thunder City with ZU-BEX and out of date cartridges. Such explosives have a shelf life not due to MB wanting to make money but because they are perishable by their very nature of use. However it seems I was wrong. As an LAE, I do not have the authority to extend anything without approval of a higher authority, that being as high as the OEM or regulator if it is outside the limits of the company exposition.
