Note that PowerFLARM did not give a collision warning (the display with dots for clock position and high/level/low indication). *It warned of the presence of the converging glider, and gave direction/range/altitude info to facilitate visual pickup. If I understand things correctly, this means that in "stealth" mode, neither of the two gliders would have had any indication of the other's presence by flarm. An interesting observation for the parallel flarm leeching thread John Cochrane

Or maybe Flarm did not compute a collision solution and thus did not warn.
Repeating for the who knows how many'th time - Steath does not suppress collision warnings.
Sigh
