jet sound - going past you at 37000 feet - weatherballoon

jet sound - going past you at 37000 feet

That was pretty cool

Yes .. Probably about minus 58 degrees C

wonder if pilots saw it ....................... probably looking inside at screens - or would on board radar pick it up ?

A white balloon 500 feet lower against a white background, you would be hard pressed to spot it without technical help.

And the case for Chemtrails gets stronger!

I did a few intercontinental trips on the RAAF 707's. Returning from Stanstead ( UK) to Dulles (Washington, DC), flying the Great Circle route, we overflew a 747 about two flight levels higher and doing maybe 100 kts faster. Up there, the air is ice-blue and almost blindingly bright, and as we blitzed the 747, the con-trails from the 747 were like pure-white slashes across an azure skin, as if cut with a scalpel. You could actually see the curvature of the horizon.

A few years ago I was launching high altitude balloons out of Alice Springs. These were big. Balloon itself weighted about a ton, and the payloads at least a ton. We needed clearance to launch and the cut down. ATC gave us 15 nm radius around the launch site and cut down position. Only up to 60,000 feet, after that we were on our own. The balloons flew at around 140,000 feet. Cutting down was fun. After you got clearance you would cut the balloon away (explosive bolts), and cut the top out of the balloon. Both the balloon and payload would fall to about 60,00 feet where a parachute would open for the payload. The balloon would just keep falling. Imagine a ton of glad-wrap falling on you. IFR traffic was ok, but we just used the BIG SKY theory to avoid VFR traffic. Basically we could drop any where from Newman to Longreach. Once we had a balloon drifting towards the Indian Ocean. There was a bloody 737 in the way, thankfully he agreed to divert. The payload ended up 200 m from the salt water. We are talking about $10m worth of payload.
