capsules are unique they can land anywhere



Not so much, Bob. If your capsule lands on water, you need some

really big ships to recover you or you sink. Note that the first

thing recovery teams did with capsule water landings was affix

floatation and stability collars. They sort of have to be prepared

for water landings. They also have to be specially designed for land

landings, else they crack open like big eggs when they hit and all

those soft humans die.



Jesus, all those airliners can't land on water, either!!! What were

we thinking???????

soyuz normally lands on ground but can land in water...

apoll capsules included flotation devices so presumably so would all capsule systems... divers would add more flotation once they arrived at the vehicle

most airliners that dich in water have heavy losses....


capsules can survive a ballistic re entry, any winged vehicle would break up under those g loads;9
