Sam allowed himself a sigh of relief before forming the visual illusion that would cloak himself and Rinaldi, making them appear to onlookers as elven pilots. Having seen the flight suit and insignia of the departed pilot made it easier to get the details right. He hoped no ground crew showed up to intercept them. The illusion was purely visual, since overriding one sense was all he could handle. Anyone who touched them would feel the difference immediately. Even sound could give them away; the imaginary clipboards hanging at their sides would not be making the normal clatter and ground crewmen would not fail to notice that discrepancy.
