No telling how many times insects evolved flight

Sure -- the winged and the secondarily and tertiarily wingless insects form a clade (Pterygota), so "one" seems like a safe bet. Or do you mean how many times the stick insects got flight back by accidentally undoing a little accident in gene expression?
