(XCOM: Enemy Unknown) Why does XCOM only have one VTOL?

I don't quite understand why my organization, with the full backing of most industrialized nations of the world, only has one  Skyranger. It seems that for humanities "first and last line of defense" we only get enough money and resources to spread ourselves too thin around the world. I can build more fighter jets and am currently researching how to build out own flying saucers. But why can't I make any more troop carrying vehicles that'd let me carry out operations in more than one part of the world at a time. Given random nature of the extraterrestrial attacks and that there's always more than one attack going on, it seems like that would take top priority over autopsies and interrogations.

You may be familiar with the single Skyranger used in the primary operations conducted by XCOM. There are in fact multiple Skyrangers held in reserve in the event that one is lost during an operation. The Skyranger constitutes the best in stealth and engine technology developed by humanity pre-invasion. This being the case XCOM conducts only one operation at a time with only a single strike team in an effort of mitigate the loss of vital equipment and personnel should they be captured and their weaknesses exposed. 

Along with this, the amount of assets brought to bear during an XCOM operation is staggering. The intelligence and information support could could easily support an entire battalion but is instead used to support the small strike team. This is only sustainable for one operation at a time due to limitations of the the command and control systems developed thus far. However this fact is most attributed to the success of the XCOM project.

Conducting strike operations may be the most prevalent, but the XCOM project is much greater in scope. The advanced information gathering and support systems are also used in support of the client nations. The XCOM CIC is linked in with the conventional military forces around the world, providing tactical and strategic support. Many XCOM soldiers, when not conducting operations, are sent as military advisers to support and train the conventional military forces in combating the Alien threat. If the situation calls for it and time is a limiting factor the reserve Skyrangers are used to transport XCOM personnel supporting the client nations.
