Tsunami- Inflatable ball

This idea is workable so long as the ball is secure in a hole about six feet deep. The ball could contain food & water. Shortages mean you have to sleep & take tiny amounts of both. Officers perhaps. Acceleration problems. Don't be hit in the head with tinned food.

Estimates of 600 mph are contradicted by footage of smaller Tsunami. They are faster in deep water & decelerate in shallow. The height of the wave will effect it's speed. The expected speed is a NATO secret.

Feedback: Officers are hoping to be in a water tight container.
