Re: "Captain America, how exciting!" TWS concept and TFA
Going to rewind the clock to the TFA Rescue Uniform.
For those that have a ground helmet and want to convert it to an airborne helmet, need to buy this kit or something similar.

Here is the cheating way first. Just insert the A yokes that attach to the leather chin cup between the liner and the helmet.
The leather liner chin strap, "the strap on the front", attaches at the same point on either a ground or jump helmet. If the canvas chin strap is sewn on then you can quit only an eagle eyed reactor will notice what you have done.
Now the properly set up liner looks like this.
Please note the front leather strap is the same.
First, the A yoke must be mounted between the liner and the suspension harness mounting brackets. This requires drilling out and then replacing the rivets. The minor danger here is a spinning rivet.
Second, The ground chin strap must be replaced with the airborne chin strap. The strap is sewn to the steel pot and has a snap dot that must face the inside of the liner and away from your head.
Third, with the canvas strap now installed on your pot, figure out where the other part of the snap should be mounted on the liner. Drill a hole and mount the snap. The danger here is cracking your liner.... it can still be used for a costume but not for jumping.
Hope this helps.
