My Two Cents
The Cargo operation did use E.T. 1900's for a few weeks. They were at first crewed by E.T. pilots until J.O. converted his crew (all in one weekend apparently). Since then he has leased a Convair from a Cape Town company (Aircraft and maintenance only), until his convairs are on line. Apparently they have got the whole postal contract and there will soon be about 7 Convairs flying around. Apparently these aircraft are acutally in existence and are almost ready to come over.
Firstly they couldn't load 2 1900's on time, the chances of loading 1 convair on time is probably zero. Never mind the paper trail. It would not be hard for CAA to find serious discrepencies and deficiencies in that operation. (Just look at the oloe extension)
From what I understand the Convair is a busy aircraft. To have fairly inexperience crew operating these aircraft may be asking for trouble.
Bottom line, start using email, and don't expect your post to arrive.
Oh well.
