I think we haven't heard RED's didgeridoo because it emits sound waves on the same frequency as the invisibility generator thingy. After the disasters of the alleged experiments with USS Eldridge in the Philadelphia Naval Yard, all invisibility generators have by NATO direction been manufactured to operate at low frequencies. Or at least, ours has, because they are so outrageously expensive that only a major World economy, or Sir William's platinum limitless Amex card, can afford one.
