Loewy's VC-137C livery has since been adapted for the larger VC-25A when it entered service in 1990, and the secondary variation (without the darker blue cheatline and cap over the cockpit) is still in use on USAF C-40, C-37, C-32, and C-20 aircraft in standard (non-presidential) VIP configurations. The presidential paint scheme can also be seen on Union Pacific 4141, the locomotive used in George H. W. Bush's funeral train.[33][2]
