Germany was *not* a mobile military. That's successful propaganda for you. Even more so in 1938. Germany relied on foot infantry and horses pre war and during the war. One of the big factors(there were several) into how they lost against the initially woefully unprepared and inferior soviets who then became a terrifying behemoth and singlehandedly crushed 80-85% of the German military and 95% of all its crack panzer divisions with their experienced crews permanently ending German armoured offensive capabilities.

Sudetenland was being rapidly turned into a literal fortress designed to hold against the Germans,Polish and Hungarians until the French,British and Russians came to help. Within just 2 years(1936-1938) they had built 12,000 fortified concrete positions split into heavy and light with another 17,000 almost completed but more than usable, this equated to around 42% of the planned number built by 1941.The Germans used these completed ones to practice their upcoming aerial(including glider troops) and ground assaults on the French and Belgian defensive lines as they all shared the same design.

The Czechs had an extremely powerful arms industry(which Germany exploited hard) and well maintained logistics with an enormous trained regular army of over 1.3 million men with thousands of artillery pieces, anti tank guns and hundreds of tanks(Pz35).

They most certainly could have held and ground the Germans down on the extensive fortifications all along the borders. After all planes can't win wars. Eventually the untested Luftwaffe rate of attrition due to losses,break downs,exhaustion, low munitions, low fuel would be too much. Czechoslovakian air force was inferior to Luftwaffe but it was designed to do ground attacks and take out enemy logistics,railways,industrial sites and bridges even in enemy territory not air superiority and would have done enormous damage in the first waves of a German assault on a fully maintained Czechoslovakia.
