I've not said anything up until now as those who think TCAS, GPS ect ect are the answer to everything simply do not listen to anything they don't want to hear. I'd happily fit a transponder if 1) I had the panel space, 2) It wasn't likely to fry my balls!
My a/c is happy low down, but I do fly high when the mood takes me. It's not irresponsible, it's simply my right. My a/c cost me £2500 to make, and it's the only thing I can afford to fly right now. The fact that those with more money would prefer me and my kind to keep out of "their" sky is a sad reflection on modern society. My answer is simply STUFF YOU! If you can't see beyond your nose, you are not fit to SHARE my (and your) airspace. If you truly think you can buy your safety, and would happily force out those that cannot, then you really can say that you know the cost of everything and the value of nothing!
