Mike Hoare got together a group of white, middle class mercenaries, and dubbed the "Ye Ancient Order of Froth-Blowers" (AOFB) after a posh English social club of the 1930s. In order for the plan to work, he disguised the mercenaries as a rugby club, and hid AK-47s in the bottom of his luggage, as he explained in his book The Seychelles Affair:

"We were a Johannesburg beer-drinking club. We met formally once a week in our favourite pub in Braamfontein. We played Rugby. Once a year we organised a holiday for our members. We obtained special charter rates. Last year we went to Mauritius. In the best traditions of the original AOFB we collected toys for underprivileged kids and distributed them to orphanages... I made sure the toys were as bulky as possible and weighed little. Rugger footballs were ideal. These were packed in the special baggage above the false bottom to compensate for the weight of the weapon."[3]
The fighting started prematurely when the second to last passenger filing through customs was found to be carrying undeclared goods.[3] One of Hoare's men was last in line, behind this civilian, and the customs officer insisted on searching his bag as well. The rifles were well-concealed in the false-bottomed kitbags but for some reason the rifle was found and the customs man, running from the scene, sounded the alarm. One of Hoare's men pulled his own, disassembled AK-47 from the concealed compartment in the luggage, assembled it, loaded it and shot the escaping customs man before he could reach the other side of the building. The plan for the coup proceeded despite this set-back with one team of Hoare's men attempting to capture a barracks. Fighting ensued at the airport and in the middle of this, an Air India jet (Air India Boeing aircraft Flight 224), landed at the airport, damaging a flap on one of the trucks strewn on the runway. Hoare managed to negotiate a ceasefire before the aircraft and passengers were caught in the crossfire. After several hours, the mercenaries found themselves in an unfavorable position and some wanted to depart on the aircraft, which needed fuel. Hoare conceded and the captain of the aircraft allowed them on board after Hoare had found fuel for the aircraft. On board, Hoare asked the captain why he had landed when he had been informed of the fighting taking place and he responded that once the aircraft had started to descend, he did not have enough fuel to climb the aircraft back to cruising altitude and still make his destination.

Hoare's men still had their weapons and Hoare asked the captain if he would allow the door to be opened so they could ditch the weapons over the sea before they returned to South Africa, but the captain laughed at Hoare's out-of-date knowledge on how pressurized aircraft functioned and told him it would not be possible.

Four of the mercenary soldiers who were left behind were convicted of treason in the Seychelles
