mr. mcgwire's answers the question it's clear enough and you had a question to what that would be to the time line of the pilot if you'd be so good as to answer that that'd be great. >> as things stand today they'll be expected to be delivered in october 2020. we'll have to look at it if you're going to issue a bafo. one thing i want to mention on the issuing of the bafo to match byd's pricing, we will not get the same bus from the other two oems. while -- we'll have to give up something. >> i don't understand that. so if we succeed in get lower price it will be a modified bus in some way? >> yes, it won't meet the range. >> i'm confused. so they're not apple to apple comparisons. >> correct. >> i guess it would be helpful to understand you mentioned battery size but is that the goal to test the range? >> director heminger's amendment doesn't give us a different bus for less. i understand it's give us the bus you were going to sell us for $4.4 million or $5.2 million for the $3.5 million price if you want to play in the pilot. is that correct? >> yes. >> you don't say take off the window
