$1.$ A quick viz of flights over time shows a drop of more than $300,000$ flights from $2010$ to $2011$:

From your experience, you know that flight activity did not drop so significantly between $2010$ and $2011.$

determine why these yearly numbers show such a large drop.

Hint: Use the $$Number of Records$$ and $$Flight Date$$ variables to investigate. Note your finding below and

paste the jpg of the viz. below it$.$
