"Black Beam" Contrail Shadow, Sunshine Coast, Australia

[Mick West]

I'm AFK at the moment, so can't contribute much. But the suggested flight sounds plausible.

I have just been for my morning beach walk and stood in the spot I was that day, the whole perspective thing changes everything. Even just changing my position from on the shore to further away from the shore, put the sun up a bit higher, imagine the plane coming at that angle NNW or whatever it was, it is a definite debunk. And the angle the plane flew, the height, the haze would also account for the pulsing effect I guess. Oh to always be able to see in 3D. Good one guys if I get 2D thinking again I know where to come. Now I will go over to the contrail threads and clean up the tiny bit of 2D thinking I have with that, it is only minimal but needs addressing. Thanks once again.

it is a definite debunk

it's actually more of a "possible explanation".

 

[JRBids]

That is correct, except I didn't see a plane, that is why I immediately jumped to the conclusion it was a laser beam..

Where would the laser beam be coming out of? What does a laser beam look like?

 

[Lisa P]

Exactly, I didn't think did I!

I just found this it was a month after I witnessed the contrail shadow.

Laser beams tend to be invisible, unless your looking straight into one. (not recommended!!) The only way you get to see them otherwise is when they pass through stuff like smoke which scatters some of the light from the beam, or when they hit something solid in which case they show a point of light on the thing they hit (the sniper laser sight 'red dot' so beloved of Hollywood action films is a good example of this)

Lasers and smoke - note they are only visible where the smoke is

"Look up!"

I took this photo 10 years ago and at the time didn't know what kind of weather conditions were required for contrail formation and I didn't know that contrails could cast shadows the way they do.

Anyway today EXACTLY 10 years later I am approx 75km north (as the crow flys) at Rainbow Beach and took a photo around midday. Most of the jets are flying at 34k to 38k feet, weather conditions at 30k feet, temp approx -42.3c and RH 91%.

I am forever grateful to Mick and the team at Metabunk for educating me on the weather. Hope you are all doing well.
