the americans did a emergency stop test on the HMS Wisconsin back in the fifties

basically on an aircraft ship they have two rudders that are able to operate independently (in case one gets damaged in battle) so as the HMS wisconsin was about to be decommissioned in the fifties they did the "barn door" test which is basically run at full speed then chuck all engines in reverse and throw each rudder 90 inwards, in effect creating a barn door that doesn't allow water to run through. the ship stopped in approx 600 metres about a tenth of what it would do normally at the same speed. thousands of pounds of damage was caused to unsecured items that smashed up inside the ship. and the rudders were f**ked and the rudder shafts bent. they did this because they were going to decommission the ship but had to fix it all when the ronald raygun recommissioned it in 1980s.
