The last thread got me thinking. How would someone get preloads through security at the airport. I would guess that you could check baggage and have them secure in your bags. I am not sure that you could go through screening without them showing on Xray at the scanner. Does anyone have any ideas or suggestions. What would happen if they are detected and you are asked?? I don't know if it is worth the risk, smaller airports are more prone to check and question. I travel weekly and never considered bringing preloads.....but it has me thinking. I may try loading some syntheselen and see if it goes through.
