A friend has a daylight-visible passive strobe on his hang glider.
To most, it would look like a small mirror ball hanging from the kingpost.

John,
Your last 7 words sum the situation up nicely ....
but possibly some genius may be able to turn this to advantage.
As I recall the original research (and of
course as we know from our own experience), the only useful
positive finding was that the reflected flash of sunlight off a highly
polished wing "was visible for miles" Unfortunately this situation really only
occurred when a glider was circling. So it is not so much a matter of
Mandrake and "smoke and mirrors", but more about mirrors!
As John McFarlane rightly notes, everything else
(at the time), was basically useless for an aircraft that could be "any colour
you like, as long as that colour was white!"
It is nice to see the CAA "giving it a go". Does
anybody know what the allocated budget for the program is?
In the meantime we are left with "lookout, lookout,
lookout", and to a lesser (but invaluable) extent Flarm.
