So, without further ado, here is my 'take' on the rocket pack and helmet:
The front of the pack, with leather straps and helmet.
The Rocket Pack itself.
The Pack in close up.
The 'Business End' of the rocket engines.
Co0ntrols on the left-hand gauntlet.
Temperature display and altitude gauge.
This is a mostly metal construction, as befits a device that would be subject to extremes of temperature, and the inevitable concussion from failed launches.
