Answer:
Airplanes
Explanation:
Commercial and Freight aviation has come a long way. From using out dated B-16 bombers for passengers we are now using beautiful technology like Boeing-747-400, Airbus A-380, and the massive and intimidating freighter AN-225. Imagine the fact that we come from a small 2 passenger glide with one propeller to Fighter Jets that can go more then 400 KM/H all over the world like the American F-18 or the American Stealth B-2 bomber. Commercial aviation also came a long way. Before we used B-16 airplanes that couldn't fly high up which caused turbulence and discomfort. The break thru in aviation was the first ever commercial airliner to break the Altitude of 43,000 feet was the Boeing 747-100.
The Allied forces land on five French beaches in Normandy.
American soldiers and French fighters march northward through France.
The Nazi forces surrender to the Allies in Paris.
The Allies liberate Belgium and the Netherlands from Nazi control.
Might be wrong but it makes the most sense when you think of marching geographically.
