Commercial Pilot Take a UFO Over Medellin? Viva Air Flight
 

Just found this video on the ufoofinterest channel on YouTube.

Even if is yet to be determined, it is a very interesting sighting; if not just for the safety and security implications.

Please move from here if not appropriate.

Just a weird looking balloon.

yes looks like...didnt imagine that a baloon like those could climb up to 30000 feet.

There are weather balloons that go over 100000 feet.

Probably another one of these, 2020 version. Looks quite similar to the balloon in the video too.

It doesn't look like the same .. but I am not a weather balloon expert ;)

Balloons?
 

On the other hand, it was remarkably like something three of observed from the office of a particular three engine aircraft (known as "The Gripper") en route LHR-FBU many years ago. It crept up on us over Drammen, (day, VMC) 4000 ft, high speed descending, took up a position just off our starboard wing for a few minutes, then sheared off to the East at very high speed. It looked slightly larger than a cricket ball.

If you slow the clip down you will notice the object turns over at one point and underneath, not unexpectedly, there she is: Julie Andrews!

The Project Loon balloons go up to 60,000+ feet

and don't forget about these ones. . . here in action over Peru

Those balloons have a transponder you can even see the Mode S altitude on the photo you posted , seen the number of them ,currently in the air not an issue (yet )

I wonder how many misses there are with weather balloons, an SR-71 crew recorded passing one in the cruise at close quarters, so about 70,000 ft or so.

The altitude of the LOON is 62,000....

Here is a picture from one at 75k

Highest unmanned balloon 173,900 ft launched from Sanriku Balloon Center at Ofunato City, Iwate in Japan at 6:35 on May 23, 2002
Highest manned flight 24/10/2014: Alan Eustace, a senior vice president at the Google corporation, reached 135,906 ft in a helium balloon and then returned to earth via parachute jump

Don't know, but FWIW a few years back we just missed one by maybe 100-200 feet at 747 cruise altitude somewhere over the north east united States.;we were close enough to discern the the instrumentation package.
