Aircraft and lightning
Following on from the Ethiopian fire thread, I assume that with an all metal airframe any strike by lightening will obey the law that sends electricity around the outside of a conductive enclosure. Anything internally will not be electrocuted or burnt. (although I have heard the 'balls of fire running down the aisle' stories)
If you have an aircraft where the fuselage is constructed using non conductive materials, e.g. fibreglass etc. how does this react in the case of lightening strike or electrical charges?
Is this something that an aircraft manufacturer will be required to take account of?
