Will it work...

...through the wires of a heated windscreen?

Reception can be very iffy at present, even with the SatNav in the corner of the windscreen where there is supposed to be a clear area.

Re: sounds great but...

CRTs are heavy because of the thickness of the glass required to maintain the vacuum inside, which is needed for the electron beam. Lasers work fine through air, so all that is required is enough plastic to keep fingers out of the way. Maybe dustproof to keep the inside of the phosphor screen clean, but there is no need for it to be air-tight.

Why?

I don't understand the rationale behind this. With the old system, you could jettison the escape rocket as soon as it was clear that it was no longer necessary. With this system, it looks like you have to carry the useless rockets around with you until you are ready for re-entry (or at least finished with everything behind the crew module). Why carry the dead weight all the way up into orbit?
