Commentary from Brian

Well it was a good flight but I'm going to declare this one over and recap the many milestones achieved. If it suddenly reappears (which one balloon did 7-days later) ill update everyone.

Milestones:


Flight Day 6 (maybe) 25-JUL-2019 21:30:00 UTC

Contact with the balloon was expected today but nothing was received :-(

This is not looking good for the flight but don't loose hope yet. FL300 (30,000') winds off the European coast have not been friendly for our flight and there are three different things could have happened:

  1. The balloon went down due to wind sheer or just fatigue from its days in the air.
  2. It stayed in the Jetstream and swung north over Ireland where airborne Amateur Radio transmissions are forbidden and the GeoFencing software shut the transmitter down until it clears the area. From there it would head further North then either turn Northwest towards Iceland or it will turn East towards Norway where there are ground stations to pick up the transmissions.
  3. It dropped out of the Jetstream as it was approaching the European coast. This would trap it in a low pressure zone and send it west again for another lap around the Atlantic where there are no ground stations.

Looking at the wind charts I think it went over Ireland then north, but whether it turns West or East after that is anyone's guess. Lets just hope it's still floating around up there

We will keep looking for a few more days before declaring end of flight.


Flight Day 5 24-JUL-2019 23:00:00 UTC

No contact received today. This was as expected! Start checking early tomorrow morning to see if the Atlantic crossing was sucessful.
