"What are we doing in the old storage wing?" Acid asks as he and Celestia walk into the open storage room with a big machine set up in the center with ponies working. Standing in the center is a mare hooked up with wire leading to a collar around her neck. A gem on the front glowing before a stallion removes the wires. She is dreased in a skin tight dark green uniform with a leather helmet and goggels.

"I said I was using your growth collar for some military stuff," Celestia says, stopping and watching from a safe distance. Acid looks over to see the mare getting the all clear before a bright light envelops her for second. The light disappears as the ground rumpels. The mare expands, and grows up to 30ft tall. The size of a two story house and towering over the others.

"This is Silver Streak, the first of the RAF's plane ponies," Celestia explains as two .9mm guns are strapped to her giant wings, one for each wing.

"RAF?" Acid asks, looking up at her.

"Royal Air Force,"

"Oh," Acid says, before turning his head as the ground shakes. Silver smiles down at him, her hoof alone bigger then him and Celestia. She bends down, gently placing her head on the ground in front of him.

"Hello Love," She smiles, keeping her voice low as possible. "So you are the one that created this cool tech eh?"

"Wow," Acid wispears in awe, looking up at the big mare. His face blushing a bright red. "How big can ya get?"

"500 feet is the saffest biggest size I can go right now," She explains.

"Is is ok if I touch your chest?" Acid asks.

"Go right ahead." She says, laying down and raising her head up to allow Acid to her fluffy chest.

"Oh my goddess, you're so soft!" Acid smiles, hugging her fluffy chest, causing Acid and Celestia to chuckle at his cute actions.

Been wanting to make a Supermarina Spitfire Mk.1 plane pony for a long time, so meet Silver Streak my size changing plane pony, the first of her kind in my head cannon. I totally didn't get inspired by a fluffy little bashful pony. Eh! %Em..% %FliegerFaustToP47%.

Anyway, I hope ya'll like my new plane pony ^{^}
