चाई गांव, जोशीमठ के निकट हेलीकॉप्टर क्रैश होने की दुर्भाग्यपूर्ण सूचना प्राप्त हुई है। जिला प्रशासन, आपदा प्रबंधन विभाग, एसडीआरएफ द्वारा संयुक्त रूप से रेस्क्यू ऑपरेशन चलाया जा रहा है। स्वयं भी पूरे घटनाक्रम की निरंतर निगरानी कर रहा हूं। गंभीर रूप से घायलों को तत्काल एयरलिफ्ट कर बेहतर उपचार हेतु हायर सेंटर पहुंचाने के निर्देश दिए हैं। ईश्वर से यात्रियों के सकुशल होने की कामना करता हूं।
