You were a Canadair Regional Jet bound for Indianapolis. I was a hapless passenger arriving late from San Francisco. You left without me. Fortunately you did not take my luggage because I never check it. But I grieve for the SkyMall orders that could’ve been. I will never forget your captivating high-bypass turbofan engines, your delicate pitot tubes and angle of attack sensors, or your cute little radome. But it will never be, because I have a confirmed seat on the next flight at 8:00.
