Ghanso Larkinson suffered from an unlucky sequence of events. The Vesians hadn't been able to get past Alex's space knight, so they turned their firepower to an unprotected mech from a nearby squad.
The Starhawk mech in question hadn't expected to be targeted by an entire Vesian squad. The knight in his squad was already shielding another squad mate, so the targeted mech lacked any form of support.
The mech blew up as soon as its pilot ejected into the distance. Some of the shards of the exploded mech happened to have hit Ghanso's mech from behind, thereby dealing significant damage to its fragile flight system
The damage hadn't been extensive, but it took a long time for the flight system to regain its functionality. As Ghanso halted the uncontrolled spin, he looked back to the Starhawk formation to see how well they fared.
