Can you imagine a world without flight? That means we wouldn’t have so many communications, including shipping, health services, internet, so much commerce, intergrated population, diplomacy, expanded eating habits, so many things. Heck, we wouldn’t have so many coffees and chocolates at our whim. One inspiration, one idea, one hypothesis, one experiment, many trials and executions, many failures, one sucess, led to all these things and more.
What a great point about never giving up. It takes 1 dream, fantasy, idea, pondering, question to lead to magic and world changing moment.
