Were there ever any female pilots / FEs? Or did any women pilots ever fly Concorde?

The world has only ever had one Concorde female flight crew member, a really wonderful lady who is known as Barbara Harmer. Barbara was an SFO on the BA Concode fleet, joining us in 1993. You can read all about her here:
Barbara Harmer - Wikipedia, the free encyclopedia

After she eventually left the Concorde fleet, Barbara became Captain Harmer, flying the Boeing 777 for BA.

Oops ChristiaanJ, never knew about B\xe9atrice Valle, salutations to her also.

I had to look it up on Wikipedia:

Quote:

Counter-rotation was achieved with the use of "handed" engines, which meant that the crankshaft of each engine turned in the opposite direction of its counterpart. The V-12 engines only required that the spark plug firing order be changed in order for the direction of the crank shaft to be reversed, according to the General Motors Allison V1710 Service School Handbook.

sorry for the thread drift.

Hi

I had a look on the eBay link and I question the engine model - the Forward Bearing supports are 5 struts but not the same configuration as the Series 200. I thought the 593 was derived from the 300 Series.

see below a picture of a 593 from Wiki:

There is Analog computer - Wikipedia, the free encyclopedia

I've done a few study exercises on a hybrid system; programming digital computers now. However when designing machines there still are tasks we delegate to analog electronics or mechanical non-linear transmissions.

hence the triplication, heavy emphasis on configuration control and high cost.

Triplication (or duplication) doesn't help against software problems unless the software itself is triplicated (which happens).
