Not uncommon for test pilots and I once knew a guy (now deceased) whose type ratings filled three certificates. But actually flying the line? One at a time is the rule.

You really don't want to fly more than one at a time. It would mean yearly training -ground school and sim as well as written/oral tests for 2 different types.

I never once said I was collecting anything. You should quit putting words in other’s mouths. Really. I just came here to discuss some things that only pilots would know. Not the media.

In 91, I flew two types as captain and one as co-pilot, but as soon as sim recurrent ran out on the third, it was dropped. Two is enough.

Only the very best can fly 2 different types at the same time.....like the Boeing 757 and 767........

As late as 1974 I was qualified on 3. B727/A, DC10/B, DC8/B.

Between this thread and your whistleblower thread that's all your doing, collecting information, becoming educated, asking questions, trying to become informed. What country are you in?

No, this is what you said, specifically:

Your syntax indicates someone who does not have a firm grasp of the English language. Specifically your misuse of articles, your syntax, and specifics such as the improper plural of "aircraft." It's a common misuse abroad. Your use of "hundreds of death" also appears to establish the same. Your use of "wanna," however, particularly to work into the syntax, does not match your other poor language, appealing to the colloquial, and suggests that you're actually a troll attempting to sound like something you're not. Your story, and your language, does not add up.

It's hard to say what your story is, but you are not who or what you claim.
