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...





How nice for it. So what? Given the one real experience with a

manned one making an accidental water landing, I'll leave that to you,

Bob. Water landing of Soyuz is for EMERGENCIES ONLY.





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





No, ALL capsule systems would not, because that stuff is extra weight

and volume that you don't want to carry unless you're planning a water

landing.





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





Yeah, and yet we fly them anyway. Getting the point yet?





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





Jesus, I wish you'd learn something before you bloviate so stupidly.

Apollo max g was around 7.2 g coming back from the moon. Aerobatic

planes hit 12 g and the wings stay on and nothing breaks up. Same for

modern fighter aircraft. Hell, even some WWI aircraft could take 7 g.



well a some soyuz have done a ballistic re entry of over 30Gs the capsule and crew survived

even apollo capsule could land on ground in a real emergency.

geez when did the shuttle ever break up on re entry?

capsules are safer, and should be designed to land on land or water in a real emerrgency....
