Cross wiring multiple explosive devices vs. single load explosive device
Never try to cross wire multiple explosive devices unless it is an absolute requirement. Instead; always focus on single load explosive devices. To illustrate this we can review the 2010 Stockholm Jihadi suicide bombers fatal mistake. By cross wiring 5 pipe bombs he had increased the chance for failure by several hundred percent. With a single load explosive device the chance for failure is approximately 20%. As you attempt to cross wire 5 of these devices you are increasing the chance for failure to 80-95%. Needless to say; this is an unacceptable risk.

The above overview obviously does not consider the approach of using “alternative” easily accessible bulk explosives loads such as LNG platforms, LNG tankers, propane trucks etc. In these cases, you would only be required to create a booster charge of 50-100 kg as the bulk of the explosives would be the civilian vessel itself.
