IT was a Bulgarian Broadcaster on the BBC world service, I forget his
name.
The Umbrella was used to inject him with a small (1mm or less diameter, I
forget off the top of my head) platinum sphere with holes drilled in it,
filled with Ricin (a rather nasty toxin derived from the Castor plant)
IIRC he died a day or so after being injected from respiratory failure.
Bye for now,
Jamie.

The name you're looking for is George Markov. He didn't have any
diplomatic post that I have heard, he was a journalist who was forced
to leave the country for his "inconvenience". Rumour is he was an
agent of an intelligence or two.

I was thinking of rutter like paddled extensions like a old viking ship... Using more
of an airfoil/wind surfer method for steering...?
Could you post or send the code for the sail...?
I'm stuck as to how you do this... It is hand code...?

A few years ago Arthur C. Clark wrote a book on the subject. One of
the articles mentioned intersteller travel using solars sails with
the assitance of space based sun driven laser systems. The speculation
was that it is possible to not only drive a craft to a nearby star
with a laser but it is also possible to return it with the same
system. You can use tacking (just like in sailing against the wind)
for the return trip. It would naturaly take longer to return but
it is technically feasable.

I seem to remember there being some involvment with the East German
Secret Police. It was really big news at the time, they were
talking about the James Bond type killing etc.

The transfer of momentum to/from a reflected photon, and thus the force
of light-pressure on the sail, is perpendicular to the sail. You steer
by changing the angle of the sail to the sun.
For maximum efficiency, i guess the sail needs to be flat.

Against the `wind' *and* against the gravity of the star at the other
end?
In Robert Forward's _The Flight of the Dragonfly_ / _Rocheworld_, the
ship jettisons part of its sail when it approaches the target, and uses
light reflected from that part to brake.
