                $html = $transport->getHtml();
                $html .= $child->toHtml();
                $transport->setHtml($html);

By default there are only a 2 options, to add it via plain xml. before the content, and after the content.

<adminhtml_sales_order_view>
       <reference name="content">
           <block type="core/template" name="test-1" template="test/template.phtml" after="sales_order_edit"/>
           <block type="core/template" name="test-2" template="test/template.phtml" before="sales_order_edit"/>
       </reference>
   </adminhtml_sales_order_view>    

but those templates will be shown in all tabs.

to insert into several parts, you have to add your template like:

   <adminhtml_sales_order_view>
       <reference name="order_tab_info">
           <block type="core/template" name="test-1" template="test/template.phtml" after="sales_order_edit"/>
           <block type="core/template" name="test-2" template="test/template.phtml" before="sales_order_edit"/>
       </reference>
   </adminhtml_sales_order_view>    
Watch out for the changed reference name. 

In the corresponding template `app\design\adminhtml\default\default\template\sales\order\view\tab\info.phtml` you can place your block everywhere you want

   <div id="order-messages">
       <?php echo $this->getChildHtml('order_messages') ?>
   </div>
   <?php echo $this->getChildHtml('order_info') ?>
   <?php echo $this->getChildHtml('test-1') ?>

The main problem is, that the sales_order_view is kinda hard coded, so it'll keep the structure.

hope that helps.

Also you can try this one as well.

you can follow the below link.http://sohelrana09.wordpress.com/2011/06/24/how-to-overwrite-sales-view-order-phtml-file-in-magento/
