Comment on the Paper On the influx of small comets into the Earth's upper atmosphere II. Interpreta

The suggestion that the Earth is being bombarded by cometoids that subject it to an influx of 3×1011 water molecules/cm²-sec encounters severe aeronomical problems. There is a serious disposal problem for water molecules deposited near 100 km. The implications for Venus and Mars also present serious problems. It is argued that the proposable is untenable.
