I was looking across some of those explicit news reports on the liquid "peroxide explosive" and came across this snark

Regardless of WHAT they were planning on using, it's HOW they'd get it on the plane that matters.

Since they've got female jihadi's too, the best way to bypass all security measures would be to have saline breast implants inserted into the females, the kind which are filled by injection after implantation, and replace the saline with a liquid explosive just prior to leaving for the airport.

This gives little time for any to leak out and cause illness to the female, nor dog/machine detectable odor since it's internal, and millimetric bodyscanners/X-rays will detect nothing hidden under the clothes.

Once on board the plane, the jihadi simply stabs the detonator (contained within a spike-like implement) into her breast (deep enough to pierce the implant sac) and fires. Close proximity of the explosive filled sacs to each other (wonderbra?) ensures sympathetic detonation.

2x 375mL @1.1SPG= 825gms of HE.

Larger implants equal greater boom.
