In some situations where the transportation of bombs involved tight corners (red circle) the Americans built by-pass roads to circumvent the obstacles

The road indicated by the arrow was installed to avoid the narrow 90 deg Daws Cross corner. Circled in red.

This road gained access to Lamarsh Park and the road to Countess Cross without the need to negotiate Daws Cross.

Known locally as the "Yankee Road".

Very unusually along the side of this road, were stored extremely dangerous "Fragmentation Bombs"
These were stored in boxes sized 4ft x 1 ft.
The bombs were approx. 6" round, 3ft long complete with a propeller.

The Yankee Road barn can be seen to the right of the road.
The case of the bomb was scored most probably by a lathe to weaken the structure on impact. The small propeller would spin once the bomb was released, after 250 revolutions the bomb would be armed.
The bombs were designed to create maximum damage to civilians above ground.

Although not armed they proved very dangerous to handle.
On one occasion at Deenethorpe airfield, the ground crew were engaged in unloading a cluster of
M41 bombs from a B17 bomb rack, not knowing the supporting shackle was either loose or broken.

During the handling of the cluster, three bombs fell to the concrete a distance of approximately 6 feet.
One of the bombs exploded, another became armed but did not explode, and the third remained unarmed.
