I was watching the TV ad for the Tempur mattress --- the one that adjusts to your body form and weight, thereby preventing pressure areas. The ad states that this mattress was developed in conjunction with NASA.........
Now, why would weightless astronauts suffers from pressure areas in bed ?? :-?

Suspect it was developed for the fat yanks in mission control......wish they would sell the info to Boeing!

;D.....good point! ;D
I think viscoelastic P.U foam was developed for flight-crew comfort during Macro/Micro-gravity phases of spaceflight rather than the orbital phase. ;)

Thank you Debs -- knew there would be a simple answer :-?
Take off & landing (ish). Out of curiousity --- how long does it take from blast off to attaining orbit ?

From the Shuttle launch pad at T+0:
Nearly 1000. MPH is reached by (circa) T+ 10 seconds, with a max velocity of 17,592 MPH being achieved at T+ 8 min. 23 seconds.......then a circularised orbital insertion* at (circa) 30 minutes later than that.
*That being the point considered to be technically "in orbit".
But THE RIDE OF RIDES is in the first 8 mins.....gawd, I wish it were me! ;)

I think the 0-1000 MPH in 10 seconds would be enough to render me incontinent. :o

On the Shuttle.....when in de-orbit phase (prior to landing) 1 hour before the 'entry interface' to the upper-atmosphere; the command "Deactivate Toilet" is given......probably just-about the time I`d be REALLY needing it! ;D

i`ve been to kennedy space centre and i am going again in sept..its a fantastic place those pads that move the shuttles are massive they make hgv`s look like micro cars.... :o

Absolutly brilliant, I don't think it could be put in better words.

I'll stick to winch launching in my glider. 400 odd BHP unleashed on 350kg is quite enough!

I agree, did 10 hrs in a winch glider when I was in the cadets. What a rush the takeoff was. Would have continued but my parents wouldent take me to chester every weekend :(

now that is something i love doing.....
Been up a few times and been in control of one with instructor sat behind......
Lovely feeling when up there, just the sound of the wind rushing by

It is very relaxing - at times, and very stressful at others. Divide distance to the airfield by your altitude to see how much you're sweating. ;)

faaaaarkin 'ell 1000mph in 10 seconds, and the 1st second looks almost stationary as it gets the bulk moving
What sort of G are they pulling Debs?

I have this vision of the pilots sunk so deep in their "tempur" upholstered seats that you can only see the hands sticking out !!!! ::)

Early Apollo astronauts were subjected to launch and re-entry forces of up to +6 g or more; however, due to careful co-ordination of the firing of the main liquid fuelled engine and the solid-rocket boosters and the fact that the vehicle performs some clever 'attitude rolls' to control sudden g-forces whilst in it`s ballistic trajectory the g-forces experienced in the space shuttle are only a little-more than +3 g which is mostly experienced on and shortly after lift-off......the post launch acceleration phase is kept quite smooth. (as 'people' tend to be quite fragile).
Astronauts still wear g-suits that prevent their blood pooling too much under flight g-forces.
I was lucky enough to fly in the back seat of a Grumman A-10 (Warthog) some years ago; sorry to say I passed-out on the first +5 g turn after take off....being tall and thin I`m not a good shape for high g. (even in a G-suit) :'(
I was indeed 'sick on the dog' upon landing too!.... :o
I`m sticking to my own little homebuilt `plane now. ;D
