I remember orvie stating that pylons were on which means time is saved when mounting the engines. I understand he is saying July, but engines don't take a month to install. Engines don't take a week to mount. He is giving a time table without explaining why he believes it will be delayed. I understand that he is generally spot-on and I appreciate his input, but alluding that the process is going to be delayed by a month because engines aren't mounted is misleading. I know just as well as anyone involved in aviation that mounting engines isn't a month long (or even a week long) process.
