aerodrome

The latest mask is meant especially for those exercising or staying active and is outfitted with an aerodrome shape so it doesn’t cling to your face and provides enough air flow to breathe heavily.

The first time I saw him was at the aerodrome at Estre Blanche.

There arrived one day at the aerodrome a large packing-case addressed "Sergeant Tam."

But apparently Fritz had overshot the aerodrome, for the next explosion came a mile to the west.
