Bristol airport

We have planned to use Bristol international Airport for some time, and today we emailed them, to ask permission for us to use the location for our first scene of our film, which is titled What Happens next.
This is the email we sent...

Hello Sir or Madam

We are 2 AS level media students, and are currently looking to film our project on Sunday the 20th (next Sunday).

We would like bristol airport to be one of our locations for our film, as it is a travel themed project. 

I am emialing to ask permission for us to film one of our scenes at the airport, as it is perfect for the type of film we are doing. we would be ariving around 12:30, and will only be there for around an hour, and won't interfere with anything important.

Cant wait to hear from you.
