FACT CHECK: Did DRDO scientist sent letter regarding failure of BrahMos missile components?

After India's successful Operation Sindoor in payback of the Pahalgam terror attack by Pakistan-sponsored terrorists, there is barrage of misinformation circulating on social media. The latest such misinformation spread by Pakistani government and its media is a fake letter in the name of a non-existent DRDO scientist.
Flagging the fake letter, the PIB Fact Check team said the Defence Research and Development Organisation (DRDO) has not issued any such letter.
As per rumoured claims, the fake letter is undersigned by one AS Kumar who is a scientist at the DRDO. The content of the letter alleged a failure in the BrahMos missile components.
However, PIB Fact Check team has dismissed the claims, clarifying that there is no scientist named AS Kumar at the Armament Research & Development Establishment (ARDE) of DRDO.
However, the misinformation campaign does not end there. Images were circulated on pro-Pakistan social media that allegedly showed debris of Rafale fighter jets of India. However, PIB Fact Check has confirmed that the images were from an earlier crash involving an Indian Air Force MiG-21 fighter jet.
Another image showed an IAF twin-engine fighter aircraft MiG-29 being downed by Pakistan. However, PIB Fact Check clarified that the visuals were from a crash that occurred an year earlier.
