Wow. Any delay at all is critical at the absolute least.
Working on Dual CC, one fall day, I was watching the trees turn colors; really enjoying myself. Coming in from the West to ROA rwy 6, approach asked on about a 3/4 mile final, "Uh, do you have the airport?" I might have well said, "WHAT AIRPORT!" My instructor let me ride it out with about 4 or 5 737s in line to clap once I got in on the ground.
Sight seeing is for the birds, I guess.
