walter said:Hi Jos
Fascinating movie and perfect illustration how tests took place in that era. No helmet or hard head and imagine any helicopter manufacturer performing tests on what seems a public road, in present times!
BTW, never know that for early trials, a different tail configuration was used.
Any more of such treasures hidden in your shoe box?
Confirmed. The USAF contract for the first McDonnell Model 38 prototype (c/n 673) carried the number W33(038)-ac-14856. I can only assume that this might have been used on the tail at a time when the type had to be identified while no official designation had yet been allocated.aim9xray said:Jos Heyman said:The two XH-20s were serialed by the USAF as 46-689/690 but the tail of this test aircraft shows the serial 14856.

The entire alphanumeric string appears to be an Army [Air Force] Contract Number, presumably for the XH-20 project. Now why would McAir paint that on the tail?

McDonnell Model-55 helicopter project,if we look to MD list,we will find
that; Model-55 was two place twin ram jet helicopter for Army.
And those drawing from the site also has the same features,may be they
wrong may be they right,I don't know.
