29. A bit of a hard landing may be intentional

Yes, you read that right! In some cases, when there is a harder than normal landing, but it’s not a result of incorrect actions by the pilot. It may be intentional owing to bad weather conditions.

For example, if it’s rained and the runway is as a result covered by water, it is necessary for the crew to land hard so as to break that layer. This is to prevent aquaplane, a situation whereby the plane slides uncontrollably.
