Blue skies

A cloudless blue sky today, & no breeze to speak of at ground level.

And yet the planes are flying & leaving their contrails – short ones only that rapidly dissipate, leaving no visible traces.

So another theory - that cloudless skies are a thing of the past for as long as jet engines fly –bites the dust (again)
