Is Boeing a buy or should I stay away?

Boeing stock is low because they make bad airplanes right now, but they should eventually rebound, and since they are involved in the Artemis space missions, I feel like that is another possible area for growth. Is it a buy? (For the long term) or should I stay away? $Nasdaq Composite Index(.IXIC.US)$ $S&P 500 Index(.SPX.US)$
