[aprssig] Coast-to-Coast Balloon Flight (non-burst?)

I think nearly all of us would like to know what prevented the 
bursting!  This group has been doing balloons a long time, both 
up-and-down and floaters and have been (apparently) perfecting their 
technique.  They launched two floaters at the same time, K6RPT-11 and 
K6RPT-12.  -12 had the type of flight they were used to, although I 
think even it exceeded their range expectations..

 From everything I've read, they were forecasting maybe Colorado, maybe 
hoping for a trans-continental flight, but certainly (I don't think) not 
expecting a trans--atlantic flight.  It was just a latex envelope with a 
low fill for low payload and plenty of room for high altitude expansion 
without bursting, a floater flight plan.

It was, however, in the end completely AMAZING to watch!  
Congratulations to the team, and a big THANKS to those hams that got the 
message and switched over to monitor 144.390 so that the balloon could 
be tracked to its eventual demise in the Mediterranean.

PS.  There's a series of screenshots of my APRSIS32 instance tracking 
the balloon both across the USA as well as across the Azores, Landfall, 
and includes a detailed zoom in on the final descent beacons.  You can
