Except we don't fly through hail that totals two planes in two months. There's $100 million right there. Maybe we should ask for more. That $46 million difference seems small huh?
Sorry Delta guys, that wasn't really a knock on you. I'm hearing your older radars are a bit of a problem.

The ironic part is that we get lined checked by the feds all the time. Maybe Delta needs a closer look at how they operate.

Not trying to knock the Delta guys; but how many times do we deviate around Thunderstorms and hear ATC ask Delta if they are going to Deviate and they say they are above the storm. Many times I see the position and say well they will be in the tops not above it. I guess this time playing in the tops of a Thunderstorm had negative consequences.

Also, Hail is very common under the downwind overhang of a strong thunderstorm - even in clear air. This precipitation which is obviously frozen, is often not detected by even the most modern radars, including ours.

I don't know which version the Delta Airbus (Northwest) radars are installed, but remember this: At high altitude, a cell may have ice particles. Reflection of ice particles is weak. An incorrect tilt may lead to only scanning the upper (less reflective) part of a cell. As a consequence, a cell may not be detected or may be underestimated.

This is why the AIM recommends 20 miles away from cells (40 miles between).

Best part is apparently the passengers could watch the storm on a weather app on their iPads, but the pilots couldn't! Another great reason not to put wifi on planes!

Before we all find our biggest rock to throw I'll repost this that Joey Meatballs posted on a different forum. A meteorologist posted a moving radar with the airplanes flight path in motion. Given the situation I could see doing exactly what they did.
