Fired for failure to falsify critical paperwork

I was let go by my employer of only 30 days this morning for refusing to "fudge" data related to critical quality control characteristics of parts. These parts are used in commercial aircraft, military aircraft and by consumer use. They recently fired 2 other people who were there only a year. I was hired on March 11th and was told I had to "do what was necessary" to get product out the door. My job as a Quality Engineer requires that I ensure strict quality standards related to ISO 9000 and QS 9000 are met. This company was asking me to copy, fudge or make up data to fill in Failure Mode Effects Analysis forms which are critical pieces of paper to identify possible failure of parts in the field.
Also, during my brief time of employment, I was given no training, never a job description, nor a set of goals and objectives were given to me. I feel as if I was fired for doing what was right and not entering false or made up data onto critical forms required by the customer. I have e-mail proof this was asked of me to do this. Do I have a case here? I am worried I don't since my employment was so short.
