Passengers in the jet transport \(A\) flying east at a speed of \(800 \mathrm{~km} / \mathrm{h}\) observe a second jet plane \(B\) that passes under the transport in horizontal flight. Although the nose of \(B\) is pointed in the \(45^{\circ}\) northeast direction, plane \(B\) appears to the passengers in \(A\) to be moving away from the transport at the \(60^{\circ}\) angle as shown. Determine the true velocity of \(B\).
