The Goodwill flight was scheduled for early June but the flight kept getting postponed for one reason or another. The primary factors causing the delays were completion of the expanded runway at Balbuena airfield, and weather conditions.

On June 10th, 1928, the Technical Commission for the flight met in the offices of the Excelsior newspaper and went over the various reasons for the contiued delays. At one point in the meeting, and after a long pause, Captain Carranza suddenly got up from his chair, went to the telephone and asked the operator to connect his call to a number he read from a small notebook.

- Is that you Mr. Rennow?..........

- Yes Sir. I'd like to ask that you send the fuel I need to the Balbuena Airfield right away..........

- If you would pelase, right away..........

- Thank you very much.  Good-bye.

With this conversation, the flight to Washington was on.

On the eve of his historic flight, Captain Carranza had dinner with colleages and friends: his brother Sebastián, his cousin Heliodoro Cárdenas Rodríguez, the mechanic from the Wright Co. that was sent to Mexico specifically to prepare the engine on the "Mexico-Excelsior", and others. At about midnight, Captain Carranza checked in to an apartment at the Hotel Ritz and slept for about 5 hours.

At 5:30 am Captain Carranza started his long day. Shortly thereafter he left for the Balbuena Airfield accompanied by his longtime friend Gustavo Espinosa Mireles, his brother Sebastián and cousin Heliodoro. They arrived at Balbuena at 6:15 am to find a crowd of supporters, among them, reporters from Excelsior, all members of the Mexican Association of Aeronautics, several aviators and friends of Captain Carranza, and all members of the Technical Committee.

Sebastián and Heliodoro conducted a throrough pre-flight inspection of the aircraft, after which, Captain Carranza boarded the airplane and flew a short distance to the new runway, specially built for this flight.

After a final smke with his closest friends, Captain Carranza reboarded the "Mexico-Excelsior" and revved up the 220hp Wright Whirlwind engine, blowing a dustcloud as he taxied to the runway.

At 8:08 am, Captain Carranza took off in the "Mexico-Excelsior". After lifting his monoplane over the 12,000 foot high mountains that surround Mexico City, he set a heading toward Tampico. Fellow aviators took off to escort the Mexican flyer out of the Mexico City valley; Major Gustavo Leon flew a Douglas, Lieutenant Colonel Alfredo Ledesma flew a 68-A, and Captain Alberto Vieytez flew a Morane.

Word of Captain Carranza's goodwill flight spread quickly throughout Mexico over dedicated telegraph lines that the Civil Aviation Department installed to follow the flier's progress:

At 9:05 am Tulancingo, Hidalgo positively identified the "Mexico-Excelsior",

At 9:20 am Huachinango, Puebla reported sighting the monoplane heading Northeast.

At 11:00 am Tampico, Tamaulipas reported Captain Carranza's aircraft. Shortly after flying over Tampico, a valve spring in one of the cylinders failed. The engine trouble caused him to lose altitude. A ship sailing toward New Orleans reported the "Mexico-Excelsior" flying very low and fast. Captain Carranza considered terminating the flight and looked for a place to land near Galveston, TX. An obstacle in the landing field forced Captain Carranza to throttle up the engine to make a second pass. At this point, the troublesome valve started working again, so he pressed on toward Washington.

At 1:45 am the "Mexico-Excelsior" was reported over Spartanburg, SC.

News of his imminent arrival in Washington prompted people to start gathering at Bolling Field, but word came that Captain Carranza had been forced to land. Heavy fog over the Carolinas made it impossible to see the air beacons along the route. Captain Carranza circled the town of Mooresville, NC and landed the "Mexico-Excelsior" at 3:30 am, just 300 miles short of Washington DC.

Aked about his landing in Moorehead City, Captain Carranza replied:

"I was flying low and fast along the Atlanta - New York postal route when I found myself engulfed in thick fog and lost track of the route. I then started circling to regain my bearings and finally saw a postal route beacon and landed there."

Captain Carranza left Morresville NC at 1:50 pm on June 13th, after receiving instructions from the Mexican Ambassador to the US. He continued his flight along the Atlanta - New York postal route, and arrived in Bolling Field, Washington at 5:15 pm on June 12th, 1928. The first to greet Captain Carranza upon landing was Major Davidson, Commanding Officer of Bolling Field.

Captain Carranza was welcomed by Acting Secretary of State Robert E. Olds, Mr. Manuel Téllez, the Mexican Ambassador, and many other officials. The following day, Captain Carranza called on President Coolidge who invited him to lunch at the Pan American Union dining room. He later placed a wreath at the Tomb of the Unknown Soldier in Arlington National Cemetery.

On June 18th, Captain Carranza was received in New York. Major Walker who greeted him at City Hall and Major General Hanson E. Ely greeted him at Mitchel Field. Captain Carranza was busy on a round of engagements that took him to West Point and many other places.
