“The study resulted in the widespread fitting of High Intensity Strobe lights to military aircraft….”
Which brought their own problems, when fitted incorrectly…..

See para 141. “Unfit for Purpose”. Pity this wasn’t declared before the accident and the kit removed. Oh, wait a minute, it was.
I recall trials 21 years ago on a laser-besad collision avoidance system developed by RSRE/DRA (whatever they were at the time). In a Tornado I think. The aim was to give warning on the HUD of power cables and similar. RAF asked that a solution be developed to a given spec (xx diameter cable @ yy range), and RSRE replied “we can already better that”. Was it ever fitted?
