Lol! First of all I'm comparing the erj with crj7 and 175 they're all plastic. DC9 was a different animal.

In the 90s and up to when gojets was started Tsa was a big and successful operation, don't know why anyone would think they would close shop. Times are different now, I'm not saying they'll get rid of the pilots(we have furlough protection) but they will get rid of the planes. And not because they want to but because they will no longer be a viable option. At a certain point our performance will go way down to where United will bring us back to 19 planes or worse. At that point we'll be on life support till the MRJ shows up.
