Zooming up into the ether till from land he might seem some mere speck in the sky had long since ceased to awake in him any nervous terrors. Instead, he reveled in the sense of space and freedom the heights gave him. Aerial intuition showed him that, within limits, the higher he was, the safer he was.

The heights meant safety from rough ground air; ten or fifteen thousand feet often meant safety from storms.
