Deletion of Spring-powered aircraft

Comment: There are very few sources that actually use this term, and none of them are actually sufficient coverage to pass the .  The only source being used is actually a mirror of this very Wikipedia article.  It could potentially be used as a redirect to Model aircraft#Rubber propulsion, where the concept is already covered, but as the term seems to be so seldom used, I don't recommend it.  That bizarre second paragraph about a steam powered aircraft was just recently added by a now-blocked user, so I'm not sure if its addition was some bizarre attempt at vandalism, or the user just ''badly'' misread the title of the article
