Upload many paragliding tracklogs to flightlog.org at once.
Your credentials are sent over HTTPS, used once to log in, and never stored. Only the resulting flightlog session is held, in server memory.
Leave blank to let flightlog.org fill these from each IGC file.
flightlog.org doesn't detect duplicates, so this tool remembers what you've uploaded and skips repeats unless you tick the box above.
