Dave, do you know the chap?

Is he likely to post some, I see you put a wink face there which makes me think you know more than I do.

Are you able to give him a nudge?

Thanks

Martyn.

I know not aimed at me, but I know the chap in question very well. He popped around to my spot over the weekend.

 

I speak to him on a regular basis, so I will give him a prod and maybe even pop over to his spot and see if I can get some copies of the documents (he lives just down the road from me).

Anyone know what the resorcinol rocket fuel was?

[Whizzbang]

I have some of the factory notes on the Bolide rocket. I'll look them out. I also have the helicopter mix somewhere as well.

Thanks for the formula's Whizzbang

 

Do you know what "meal A" was as opposed to ordinary meal?

[Arthur Brown]

Apparently some of the Astra rockets were rammed on a spindle, but some were rammed solid with clay at each end and then pierced with a pointed tool to force the formation of a tapered burn chamber.
