Are commercial airplanes really susceptible to liquid bombs?

Richard Saferstein (Former Chief Forensic Scientist) gives expert video advice on: What is dynamite and how does it work?; What is an ammonium nitrate explosive and how does it work?; What are homemade bombs and how do they work? and more...

Yes and no. A liquid bomb or a liquid explosive can be made by an individual if they desire to. However the ingredients of these explosives or liquids are difficult to come by, but if an individual isn't so inclined it can be done and for that reason we have to be aware and on guard.
