* By and large it's SoOkayItsAverage, but it has some creepy stuff in it. A small, twin engine plane flies up to go over a storm system, only to encounter a huge wall of black clouds that it can't avoid. Okay, [[DarknessEqualsDeath ominous]], but not too bad...until they realize that they've been flying through the storm for a while, and it doesn't seem to end, and their altimeter says they should be in the stratosphere, and all they can hear on the radio is this horrible screaming sound. But what '''really''' freaks you out are the [[CombatTentacles brief]] [[MoreTeethThanTheOsmondFamily glimpses]] we got of [[EldritchAbomination the thing that makes the screaming noise:]] [[GiantFlyer something]] ''[[GiantFlyer huge]]'' [[EldritchAbomination moving around in the clouds.]]
