Yes, theoretically they could be either. Either contrails, trails of ice crystals that indicate where there will also be exhaust chemicals in the air
from a passing jet (though the absence of such a trail does not also indicate the absence of these exhaust chemicals). Which have been recorded,
sampled and studied in huge depth for 9 decades.
Or they could be chemtrails, deliberately sprayed by aircraft, but for which the composition, manufacture, storage, operating systems and even the
reasons for it being done are ALL subject to widely differing speculation because nobody can point to anything definitive after at least two decades
of constant global operations.
But why the firm belief in the latter over the former?
