/yes, and ? gdal_translate returns in error as expected due to the 
missing tiles. If you want HTTP 400 to be silently ignored, you can do:/

/gdal_translate 
"WMTS:https://basemap.nationalmap.gov/arcgis/rest/services/USGSImageryOnly/MapServer/WMTS/1.0.0/WMTSCapabilities.xml,layer=USGSImageryOnly,tilematrixset=GoogleMapsCompatible" 
tmp.wmts -of wmts/

/and edit tmp.wtms to add 400 in <ZeroBlockHttpCodes>
