Sorry folks-newbee and non tech.
On the concorde- both sides are 2 hex dark areas near the front doors. I understand they are static discharge areas-but maybe I am wrong. Can someone explain to me a) are they really static discharge areas. b) why so large compared to other aircraft-I do not see dark hexes like that on other plane-or maybe I am looking in the wrong spot....
I have checked past postings but could not find the answer
there is economy class, business class, first class...then Concorde..pure class

You are confusing electrical static with pitot-static.
The panels on Concorde are static ports for the Air Data Computers (ADC). They are flat panels that have a number of holes in them that connect up to tubing that feed the ADC's with static air pressure.
On all a/c this area has to be maintained very carefully to ensure the ports do not become distorted and the pressure they sense become influenced by dynamic pressure i.e. ram pressure from fwd flight.

On a serious note, if anyone sees the static ports covered with tape or blocked in anyway after cleaning has been done or mx carried out or just when it doesnt need to be there, REMOVE IT !!, if a/c departs with blocked pitot static ports, a/c is in trouble. especially in low visibility, I believe there has been a fatal incident relevant to this.

Aeroperu 757 crashed for the same reason (1996?) and Boeing was being blamed again. Since that crash, Boeing issues brightly colored Static Port Covers and recommends not to use tape. The Aeroperu mech (untrained and unsupervised) used duct tape. Not the brightest ideas on a metal colored plane....
