You can't really blame the chaps - there are still quite a lot of airfields that ban microlights still (Thruxton or Biggin to name two) and some very experienced pilots are very-closed minded about them. I must admit, as somebody who flies most things, it irritates me sometimes that I can go somewhere in my (unsilenced) PA28 that I couldn't in my (silenced) flexwing, presumably my airmanship is similar regardless of what I'm flying.
And this is definitely getting off-topic, so I'll belt up.
