Whats the big rush anyway, what with the menzies/equity debunkle, crappy service at airports, luggage probs and the lot, no one is ever on time anyway, so a slower aircraft departing is surely not that much of an issue.
I often get pissed off having to approach behind the heavies at Smuts when I am flying a turboprop, because whereas I can offer 220kts to 1.5 nm, I have to fit in behind you 140 kt approachers and make my passengers late. Inconsiderate non GA drivers.
Im just yanking your chain, but I do believe there is room for everyone. I feel that weak controlling is the problem in most cases.
