Before Obama’s trip to Vietnam, chopper Marine One was brought to Hanoi for escorting and emergency rescue on the president's route from the airport to the hotel and vice versa.
However, Vietnam’s air force didn’t accept this option, reassuring that aerial security would be kept during U.S. President’s trip. Marine One then stayed behind at Noi Bai Airport in case of emergency.

Vietnam also didn't accept U.S. security’s request to have snipers deployed at vantages points around the airport and the venues on Obama’s agenda, or to check Vietnam’s diplomatic cars in the receiving delegation.

Two days before the trip, security force at Noi Bai Airport cooperated with local police to inspect the roads around the airport. Twice a day, Vietnamese soldiers searched for landmines and bombs.
Vietnam was in charge of aerial authority but allowed a U.S. secret agent in the control tower to monitor air traffic controllers.

All doors were shut
Residents living along the road facing Noi Bai Airport were requested to keep all doors and windows shut.
Vietnam and the U.S. sent 200 security officers to the airport and hundreds of police officers have been mobilized to set up outer perimeter protection.
The U.S. security force also installed jamming devices to prevent remote activation of explosives. Both countries’ security forces used a secret frequency to communicate.

After the U.S. President left the airport, the two Air Force Ones and Marine One chopper were put under strict protection.
Fuel for these aircrafts was thoroughly checked and sampled before and after pumping. The aircrafts were required to be parked in an all-day floodlit area and under continuous CCTV surveillance.
Obama traveled to Vietnam on May 23 for a three-day visit marked by a historic lifting of U.S. lethal arms embargo. He is the third U.S. President to have visited Vietnam.
