I am not advocating RJs here, but if we got them, the Sukoi Superjet seems the only choice. Look at the cockpit. Looks as EXACTLY like an Airbus as possible. Wikipedia says Boeing was consulted. Clearly this is a lie. It was Airbus. Sidestick. ADIRS. Flap handle. "Retard, Retard." The list goes on.

The only bizarre thing is the RA random countdown.

Again, not advocating RJs here, but this is a pleasant distraction and IF we ever got them, this one looks like a quick transition.

Southwest is arguably the most successful domestic carrier.. And they fly one type. Here's to a fleet of 500 Airbuses.
