Absolutely mark ten, probably the biggest threat to the viability of vegetative bacteria is UV light.
The following extracts, taken from a Porton Programme Report (17/60 see below), give a more accurate description of the parameters surrounding the
large-scale dissemination of Biological Warfare (BW) agents.
Item 1. It is believed that the most effective travel of aerosol clouds of potential BW agents would be limited to the period when the
sun is below or only a little (ca 15 degrees) above the horizon, as most bacterial organisms succumb rather readily to exposure to
daylight.
Item 6 then rather chillingly states:
6. ….Source emissions may be made in late evening or very early in the morning depending on meteorological conditions and on which
aspect (night travel or morning fumigation) is of greatest interest.
Of course the spraying of bacteria in the hours of darkness is not an absolute rule. Anthrax spores aren't affected that much by daylight, as are
other sporulating bacteria, and could remain viable if sprayed during the day.
Or the bacteria could be coated with a protective substance which would delay the effects of UV. Research of this type was undertaken by the MRE
Porton Down scientists during the later Dorset Defence Trials (aka the Lyme Bay Trials). During 1967-1968, a protective substance was added to the
bacterial suspension prior to spraying the South Coast. This proved quite successful in protecting the bacteria from ‘polluted air‘; there is no
reason why a protective coat against UV could not have been developed.
A third possibility is that the substance being sprayed is not a bacteria, thus making UV associated problems irrelevant.
Should anyone else want to read the Ministry of Defence commissioned Independent Review of the Porton Down public area live bacteria experiments which
were conducted 1963-1975 then

Interestingly, the MOD appear to have removed from their website a similar MOD commissioned Independent Review of the earlier Porton Down public area
BW experiments (the Large Area Coverage Zinc Cadmium sulphide trials 1953-1964).
This review was conducted by the Academy of Medical Sciences and has attracted criticism for not examining all the experiments, especially those
experiments which contaminated large city populations.
Whether the removal of the review from the MOD website is connected to the recent adverse publicity surrounding the Porton ZnCds experiments,
conducted at Norwich during 1963-64, is unknown.
You do raise a very interesting point Mark Ten.
Are chemtrails often seen at night?
