Fafnir

There were no aircraft outside or visible at Old Warden this morning, but this monster was stationed at the open doors of the hangar.  It had something of the ghostly mask about it, so it was rather noticeable.

It is apparently equipped with an "aero engine" of some 100hp.  It is very old and very valuable, it seems:
