A1 has front court status. A1 passes the ball to A2 who while jumping from backcourt and in midair catches the ball and lands in front court.

1) Does this become a backcourt violation when A2 catches the ball or when he lands in Frontcourt?

2) Does the subsequent throw-in occur at 28 ft mark of B's front court or B's backcourt?
