It's a no-brainer. Everyone who flies gliders with other gliders
needs to get a PowerFlarm. Everyone who shares airspace with
airliners needs to get a transponder. It's just that simple.

The SSA rules committee needs to immediately adopt a mandate for
PowerFlarm in 2011 sanctioned contests so that the Flarm folks
understand their mission and can get production ramped accordingly.
Let's not have any more mid-airs -- they are ruining the fun.

A big thank you to Darryl for his extrodinarily clear explainations of
a complex subject.
