Where's The Shuttle?

On Wednesday, space shuttle Discovery returned from the International Space Station for the last time. Discovery's landing path took it very close to Cozumel. We received a telephone call from our friends here advising that we might be able to see it. Wow! Bob and Lynn had witnessed a previous shuttle zooming by just west of the island. We all got busy checking the NASA site and as the countdown kept ticking, we just couldn't figure out a way to get some detail on the flight path map. All we knew was that it would fly by pretty close, skirting Cuba on its way to Florida. So, we went up to the roof with our friend, Laura, our binoculars and our phone. Dick, Gwen, Bob and Lynn also made the climb to their rooftops as well. All to no avail - no stream of condensation, no mirrored fleck in the sky, nada, nada. The shuttle had apparently without our help gone by about 100 miles to the east of the island. So, we again squandered hours with nothing to show for it. A real switch from our normal productivity?
