Hypersonic Aircraft Contrails?

Today (May 15) Amateur Meteorologists on a website spotted a unusual phenomenon that appeared on Satellite imaging websites. Conditions at the time meant the cloud shelf wasnt breaking nor was it high shadows being cast upon lower clouds.
The only explanation was that a "rip" through this cloud-layer was as a result of a Aircraft either cloud-seeding or hypersonically tearing through the cloud and its wake being left behind.
One Meteorologist reported hearing a deep boom around the same time as these images started to appear, and no military activities are scheduled today except in the Far East of Europe.

Does sound like some sort of Super Sonic craft! But if they are shure there is no military activity in that particular area, could be down to secret organization or Aliens! ooooh

ok - first can we have some sources for these claims ?

and second can we have a definitive claim ? " it can only be a hypesonic aircraft contrail OR clouad seeding "

WTF - neither of those alleged " explainations " is even logical nevermind accurate

where was this ` boom ` heard - as the alleged anomolie runs right through central france

I dont know if I can link to other websites, but here is the discussion on it.

One has to be suspicious of claims about hypersonic aircraft. While it has been proven that they can be built and flown, doing so on a regular basis would be very difficult and prohibitively expensive. Even for a black program.

The main reason is that there is no safe, reliable and reusable method of thermal protection for the airframe. The best type still available is like that on the space shuttle, which is very delicate and must undergo extensive repairs after every use.

The original post presents a perfect example of a false dichotomy. Clearly those are not the only two possibilities for this image. It seems like the consensus on the other board is:

it is the upper frontal cloud casting a well defined shadow onto the lower stratus sheet below.

The OP claims that this is impossible given the conditions at the time. Is there any actual evidence to support that assertion?
