“Sheesh, Cloudsdale sure aren’t holding back for the first snow of the season, are they? Lucky you made it here before the blizzard really picked up, eh, Snowbutt?”  
“Psh, this kinda weather doesn’t trouble me much, just isn’t too safe for me to be delivering when it’s all windy and white-out like it is… and I’ll never pass up free hot chocolate.”  
“Heh, of course. The hangar ain’t much, but it’s at least better than how it used to be now we’ve actually got a front and some doors on the darn thing. Don’t think I’ll be making any mail hops until the storm’s over, either way.”  
“I’m just still surprised you can keep warm being on the front of that thing, doesn’t it get really cold when you’re up there going that fast? Especially when you’ve only got a jacket on.”  
“Heh, believe me, a sixteen-cylinder cider-fueled compression combustion engine kicks out a lot more heat than you might expect. Still need to keep the fuel from gelling up at startup, but hey, it’s something. Have been trying to find a blanket or something to fit around the flight stick, though… well, the cold down there at least does keep me awake, if nothing else, eheh.”  
“Mmm, yeah, I… don’t think I needed to know that.”  
“Sorry.”
 
So, as some of you might know, Winterlight’s job when he isn’t a massive pile of chub or big squeaking balloon is being one of the local post-ponies, working for Equestrian Royal Mail. He only mostly covers Ponyville, however, so when a small package or some letters need to be transported further away, what better way to send these than via an express mail system like an excessively overpowered high-wing monoplane owned by a cheerful and moderately heavily armed pegasus? Night Strike might like flying her Stork around for fun, but she’s gotta eat, too! And fast air mail is one of the things she’s more than happy to take on responsibility for.
 
…at least, as long as the weather permits it, anyways.
