The 747 will remain the Queen in my eyes. The A380 looks like an A340 with a glandular problem - there's just something about the 74 that means I can't look away when I see one landing or climbing out.
The 727 is a bit before my time - but I'll stop what I'm doing to listen to them take off and climb out here at ML (haven't seen one in a while), or CNS on the odd occasion I'm up there.
