A blast from the past. Real nice OMEGA nav module. Ahh, the good old days. We'd take off from ORD aimed for Cancun using the 727 Omegas that UAL bought at some flea market for $40 each. It worked just fine for a thousand miles, and then just like magic as soon as we left land at Grand Isle to head out across the Gulf of America, formerly known as the Gulf of Mexico, the bastard would quit. No problem, SOP, fly a 158 heading until we could pick up the Yucatan Peninsula on the weather radar. We never missed by much, and Cuba was just off the left wing if we got lost. They'd launch some piece of crap Russian Glomstogort 32 to intercept us and guide us to Mexico. Well, I made that last part up.
