[TheForge] TheForge Digest, Vol 63, Issue 58

[Jacques Bourret]

Hello everyone! 

I need a translator french english for to write to you. 

I am new to this newsletter. I tell you that the pictures of Cindy and James are beautiful. I  talk of pictures of France in 2008. 

I  would like some details on the photo 13. I see a picture of a door with old hinges. 

Thank you 

Jacques

> PSP has hooks that hook into the piece adjacent to it. It is laid like 
> bricks so that ends butt and joints are staggered. It has holes punched 
> in it for weight reduction and the punch was the type that carried lots 
> of metal through to the back side which helped stiffen the plank. As I 
> recall they were about eight feet long. (I never carried one or 
> examined them except from the cockpit.) They were laid over soft ground
> so aircraft could land and take-off. Kolie field on Guadalcanal was 
> all PSP even the taxi strips and the revetment areas. If an aircraft 
> got off the PSP it would sink until the wing tip started to take the 
> weight. It was a big project to get them back on the PSP. Usually, Jack

> roll. The CB"s built them in less than a week. Bouganville was PSP and 
> I believe Buka was also but I never landed there.
> PSP would roll up like a wave in front of a B-24. It made Take-off and

> way to start a mission when you lose and aircraft at home prior to 
> departure.
> PSP was available on civilian/surplus market after the war. There must 
> be some of it somewhere that could be purchased if cost was not a factor.
