Grimes Flying Lab

It’s official: the amazing Grimes Flying Lab will be at Mansfield Airport Day!

What’s a flying lab? It’s a Beech 18 that served in the Air Force as the C-45. Built in 1952, this C-45H was a valuable tool for Grimes engineers to test and evaluate aircraft exterior lighting systems under various conditions while actually in flight.

Grimes would fly over to Boeing and show them the different combinations of lights available! It currently has over 75 lights on it!!

This incredible aircraft is part of the National Aviation Heritage Area! Come visit the Grimes crew on Airport Day and learn about this Ohio aviation treasure!
