On the morning of 29 March, 2 World Airways Boeing 727s flew from Saigon to Da Nang to attempt to pick up more refugees. When the first 727 landed at Da Nang AB it was mobbed, 270 people pushed into the plane, all but 3 were ARVN. As the aircraft attempted to take off it was hit by a grenade which jammed the flaps and the main runway was blocked by trucks and the pilot instead took off from a taxiway. A number of ARVN hung onto the undercarriage and in the wheel wells, preventing the retraction of the landing gear, 4 of them survived the flight back to Saigon.
