Please describe in detail, step by step, the date and time of my arrival at Bole International Airport in Addis Ababa, Ethiopia, from Washington Dulles International Airport, and specify the aircraft I took.

The departure board at Washington Dulles (IAD) flickered with the crisp, cold promise of a long-haul journey. You stood near the gate, ticket in hand, watching the sleek silhouette of a Boeing 787-9 Dreamliner being prepped for the long trek across the Atlantic. This was the flagship of the Ethiopian Airlines fleet, designed to make the eleven-thousand-kilometer journey feel like a mere heartbeat.
