Contrail vortices and irisation from the last few days

All photo's were taken in Amersfoort, Netherlands.

Some good shots of a tricky subject (irridescence) there! I've never managed a good shot due to flaring issues etc.

Contrails are always interesting, and many chose to ignore them, but they can generate some good effects, as seen here. I saw a good example of vortices last April, they don't last long so you have to be quick!

Those first few photos look like the elusive donuts on rope contrail, in military aviation spotters circles these are trailed by the americans latest black programme and top secret hypersonic stealth plane and have been seen over the north sea,looks like a black triangle apparently
