Any of the "Chuck, is that you?" strips are my favorites! I and a few others are attempting to turn that into a running gag on ATC frequencies. Just the other day I listened to an FO mistakenly give his before landing passenger briefing on 121.5 in both English AND Spanish! Sure enough, once he ended I keyed up my mike: "Chuck, is that you?" was broadcast out over the south Texas countryside.
I don't know how to access the archives, but my favorite series of strips ends with Chuck being intercepted over Washington DC by F16's and one of the fighter pilots has a sign that read, "Chuck, is that you?" All Time Classic!
My other favorite would be when Chuck and Julio were bringing the Twin Otter into Santa Barbara, and when Approach asked for their position Chuck replied, "Approach, I am Chief Pilot at Roost Air". "Chuck, is that you?" was ATC's response, natch!
This week's strip ranks right up there too...
