I've been lucky enough to experience 2 FJ flights during my time in the RNZAF.
A Strikemaster doing gunnery and bombing. I found out that it is possible to vomit in 5.5g. I didn't know my stomach muscles were so strong.
A Skyhawk where we were the night flare bomber. Vomited again due to disorientation and vertigo.
My utmost respect goes to the aircrew who do this every day. I couldn't!
Even with the throwing up I, to this day, remember every detail of these flights and feel very privileged to have done something that 1 person in 10.000 has experienced.
