Kevin is guiding the jet down when Michelle floats up beside him. As it touches down, somewhat roughly, grappling lines shoot out and attach themselves securely to the train, locking the plane fairly tightly in place. The engines start to power down.
Over his radio receiver he's been guiding the plane through, Kevin hears Titan bark out, "Sanchez! Abort landing! It's unstab...!" just as the train gives a huge lurch to the right! The hoverjet, locked firmly in place, adds to the momentum as the car starts to roll. It's connectors to the cars behind it start to break apart, leaving the other cars safely on the track as the lead car tips wildly.
And not only in combat. Damn, it was simple, just be sure the train is stabilize before the jet lands. Lucky Titan was there.
