The 2^nd Air America taken up after the CIA airline had been broken up, below had no connection to the CIA and the Bolivia information on CP-1387 is probably wrong.  See previous post                 http://flyhelio.com/smf/index.php?topic=554.msg2966#msg2966

Doug, you are doing an amazing job finding and posting all these great articles.  Thanks!

[Doug Johnson]

I appreciate the accolades but the majority of the articles were found by Gordon Cragg.

He loaned them to me. I  took them to a print shop had them scanned to PDF files.

I intended to post them as PDF files that you could download and read at your leisure.

But Gordon has the site set up so only small PDF files can be posted, and even as individual pages most are to big.

So I converted each page to PNP (Picture files) then since their is a weird limit of a maximum
file size of 2 megs and a Maximum total of 6 megs for the site. I had to cut each page in half and if they were
close to 2 megs each I could only post 3 uploads per post instead of 4. That's why its taking so long to post
them.

I'm stubborn so I've plugged along at it.

Fortunately for me unfortunately for you I only have 3 more stories left.

I guess I'll post some Factory advertising handouts next.

I posted some pictures sent to me by Scott Seibold owner of 1232

Restoration of Tim Green's Stallion.

It gives a good look at the construction of the first two prototype H-550 stallions.

This is probably the last post on this topic it has gotten too large, takes forever to load.
