Flight Data:

Data for AE0SS-11 fails above 30K meters and data for K0ANI-11 failed to make it to Findu after it passed 40K feet during descent (apparent dead battery). So, I've created a combination spreadsheet (ess099_comb_Flight_Data.csv) that contains packet data from both APRS systems and the KPC3 on board log file which results in coverage of the entire flight from lift off to touchdown.
