Winginitt, I think others have made it abundantly clear- This is about secondary safety, not primary. Primary safety is a given for this conversation. If you have nothing to add about making a aircraft safer in a actual crash- please desist. You are only going over rehashed ideas and stopping others from contributing and gaining some useful knowledge. Forum members often stay back from commenting, when they feel others are pushing a agenda that is not on topic. This is beyond thread drift. If you wish to push your view - start a thread on your topic. This is a community forum- not a platform to shout your ideas. This is a friendly reminder, please accept it. Moderators /staff may be less polite.
