the ju-87 (or stuka) was a german/nazi dive bomber that was in air until 1940. The wings consisted of sheer metal and cloth. The siren (or Jerichos trumpets) was built to sound when the ju-87 was diving to bomb enemy tanks and soldiers. The cockpit consisted of fiber glass strong enough to take a 50. bmg bullet and not break. The rear gunner would face the pursuing planes. sadly... due to america there is only 2 still in top condition out of the 3 left on this world that arnt blown up. -MOAU
