Why didn't you edit it then instead of just adding a tag?Richyard 14:25, 13 September 2006 (UTC)

I fixed a spelling error and removed the tag. Gfloner 07:25, 18 February 2007 (UTC)

[edit] Pressure required 3GPa ?

It is stated "Simulations of a flow at 5.5 km/s, 45 km altitude would require tunnel temperatures of as much as 9000 K, and a pressure of 3 GPa.". I think that a pressure of 3 GPa (30 000 atmospheres!!!) is far too high, instead 3 MPa is more realistic (see further sections of the article). Also some quick calculations (adiabatic expansion) show that 9000K and 3MPa is more feasible. Any experts around? Regards NickFr (talk) 20:34, 30 December 2007 (UTC)
