I'm sure that most GA pilots are
aware of some of the impacts of delays on commercial flights. But it's whether those pilots
care about those impacts. It's not too difficult to find GA types who will gladly 'get in the way' just because they can. Thankfully I'm not one of these by the way
Safety is of course number 1 priority in all manners of aircraft operation, and it is true that if someone has an issue with proceedings, it should be dealt with by contacting the controlling agency not directly to the offending aircraft. In this sense the slower aircraft would simply be following instructions, perhaps oblivious of the proximity of the monster up his chuff. Reminds me of the old BT slogan: it's good to talk!
Well said Jollyrog!
