HAHO
Guested for HATS Boscombe on a 35000ft HAHO trial at CLake. Lots of discussions with geeks ref pressure altitude density altitude IAS TAS pre-breathing etc. Best bit was that a spare crew had to be on standby after landing for a few hours and the decompression chamber had to be available at NAS San Diego. If any jumper or crew went down with bends type symptoms the spare crew had to fly everyone to SD and everyone had to go into the chamber with the casualty and be sorted. Imagine being in the chamber, knowing there was nothing wrong with you, and that the spare crew was now down in the Gaslamp area!!!!
