Corrections
3 Challengers; 3 Globals. BBJs are gone, have been for a number of years.
Flight department is actually too small...they outsource about half their flying because they don't have enough airplanes/pilots to support the required corporate travel. They are short a pilot or two but hiring is on hold due to stock price, general US economy, and misguided perception that all corporate aviation is evil.
There are no lead/chase airplanes or other UFO-Conspiracy-Theory wastes of investor money. They primarily use the Challengers for domestic flying and the Globals for global (get it?). There are usually several pax per flight; could even be full.
My sources tell me GE keeps the flight department because:
1. It helps them run the business and make money.
2. They can't always fly via airline to the worldwide places they need to go, at least, not in a business-competitive way.
3. They (senior leaders at one of the world's largest companies) like knowing that their pilots are GE employees and screened/trained to GE standards (which are high, by the way).

I'm more impressed that you were able to figure out who the previous was.
