No, why? Aribus and Boeing make a lot of the big planes. But they are far from the only game in town for making planes at all.

Even fewer planes isn't much of a problem. There were much fewer planes in eg the 1950s than today. But no one thought that would mean humanity would forget how to make planes.

Also bankruptcy isn't the end of the world. In some sense, it just means that the creditors take over control of the company from the shareholders. All the factories and engineers are still there.

For example, airlines go bankrupt all the time.
