Being a fan of scented candles, I've often wondered if there is a way to "capture" more savory scents, and infuse them into an oil or cellulose to recreate as a custom scented candle? Examples would be: the smell of sauteing the holy trinity (onion, bell pepper & celery). Or freshly popped popcorn. Or the smell of new rain on hot asphalt. Any ideas?

Aircraft have stall speed. For some WWII fighters it was 110 m/Hr. If the speed drops below that, the aircraft drops down like a piece of junk. I remember an episode in California when a small private plane flying over a residential area all a sudden stalled according to witnesses and went into the ground. Perhaps the pilot failed to maintain the proper speed. To avoid this sad outcome the pilots in WWII had to open up the throttle a bit more and increase the power of the engine(s) and thus the speed.
Well, how about the military gliders. On D-day in Normandy hundreds of gliders flew from England to France, packed with people in military gear, sometimes with the addition of jeeps and other machines and nobody dropped from the sky unless shot down? How come they maintained the proper speed? What is the secret? Thanks, - AboutFace 22 ( talk) 21:56, 29 November 2020 (UTC)
