Where did I say that rag and tube types are infringing???
I'd expect "vintage types" to rarely infringe airspace. Most rarely fly and when they do they don't venture very far and stick to the well travelled locality.
Other "rag and tube" types (microlights) generally won't get picked up on radar and when they do there won't be any altitude info so level busts won't be detected.
I'd expect most infringements
per hour flown to be done by low time VFR pilots who did their PPL years ago and are not up to date with current developments in flight planning.
I'd also expect high-hour operations to feature prominently, simply because of the extra time they spend airborne. The UK PPL average annual airborne is so appallingly low that people who fly 300-1000 hours per year could well account for a lot of infringements. But the reasons will probably be different; they won't be busting airspace because they couldn't find the M25
