• Boeing's airplanes orders and deliveries data from 1955-2022 contains full information about the customer, operating country, model's name , delivery year etc.
• We use PostgreSQL to see which countries had the most orders of Boeing planes in the period of 1955-2022 and which companies failed to receive their orders or didn't receive them on time. Also, there are some airline companies (customers) that did not receive the number of planes that they had originaly ordered from Boeing company. So, we estimated the probability for each country not to receive the order that they initially placed.
